25. anonymous

*Clears throat*

26. saifoo.khan

Alright! Let's begin.

27. saifoo.khan

Do i sound like one? lol. ;)

28. saifoo.khan

That's cool. Most people on OS are Christians. I'm a Muslim btw.

29. saifoo.khan

Alright, so moving along. I want you to learn how to solve them step by step so that you can solve rest of the problems on your own.

30. saifoo.khan

Sure it is. ;D

31. anonymous

:( okay

32. saifoo.khan

Why are you sad? You should be happy im helping you learn. lmao.

33. anonymous

Yes,I am, but, what if i do the rest except one and you check?

34. anonymous

because,earlier you were going to leave after explaining right?

35. saifoo.khan

Question 6. Ask me where you're stuck. 10, 18, 26, 34, 42 T = a + (n-1)d Where a is the first term. n is the term you have to find. And d is the common difference. Step 1. Find d. subtract any 2 adjacent term. Let's say 42 and 34 42-34 = 8 So d =8 Now insert the values in the formula. T = a + (n-1)d

36. saifoo.khan

I still have to leave. Will do in 10 mins. Just staying to help you learn.

37. anonymous

ok,thanks

38. anonymous

reading"

39. saifoo.khan

Sure.. take your time. Till then, im going to the kitchen.

40. anonymous

ok.

41. anonymous

saifoo?

42. saifoo.khan

Back!

43. anonymous

o ok:)

44. saifoo.khan

So?

45. anonymous

Umm, im in pre algebra, could you explain it in a simpler way?

46. saifoo.khan

But dont you'll be needing the same formula to find term?

47. anonymous

I dont know,we were only given this just today

48. saifoo.khan

Hey wait! i just found out there is q1-5 too! lol.

49. saifoo.khan

Solve that first.

50. anonymous

lol yay!!

51. anonymous

awwww.you are a strict teacher

52. saifoo.khan

lol. Okay. So for "nth" term, there's a formula. T = a + (n-1)d Where a is the first term. n is the term you have to find. And d is the common difference. You have to learn this formula. If you're through till here then i'll move forward.

53. anonymous

Okay.

54. anonymous

its the same for all of them?

55. saifoo.khan

Okay. So what is d? it's the common difference. To find it, subtract any two adjacent terms. Let's say 14 -11 = 3 Hence, d = 3

56. saifoo.khan

And yes, it's same for all.

57. anonymous

ook.

58. saifoo.khan

This is a lifetime formula. Will help you in college too. lol.

59. anonymous

let me try no.1

60. anonymous

lol

61. saifoo.khan

Sure.

62. saifoo.khan

I had to sleep at 5. And it's 6:35am. -_- Kill me!

63. anonymous

ok. 10+(70-1)8

64. saifoo.khan

Wow, nice.

65. anonymous

lol. Sorry to hear that, i know what that feels like.

66. saifoo.khan

Haha. :/

67. anonymous

:S do i write what i typed down?

68. saifoo.khan

Write it this way: T_n = a + (n-1)d = 10 + (n-1)8 = 10 + 8n - 8 = 8n + 2 Next, insert 70 in place of n.

69. anonymous

what does t mean?

70. saifoo.khan

it's just a short form of writing term. just like hmp is the short form of @helpmeplz311

71. anonymous

and may i see the link to your tool? i think ive gone there before

72. anonymous

lol:D

73. anonymous

howd u ever guess? lol

74. saifoo.khan

My tool? o_O I have a tool? lol.

75. anonymous

lol u said ud found a tool for the qs?

76. saifoo.khan

77. anonymous

78. saifoo.khan

When did i said that? lol. I forgot. Literally.

79. anonymous

look

80. saifoo.khan

Where? lol

81. anonymous

lol,scroll up..12 mins ago..

82. anonymous

See it?

83. saifoo.khan

lol. Okay. So for "nth" term, there's a formula. T = a + (n-1)d Where a is the first term. n is the term you have to find. And d is the common difference. You have to learn this formula. If you're through till here then i'll move forward.

84. saifoo.khan

Sorry, no.

85. anonymous

'hey wait i found a tool for q1-5'

86. saifoo.khan

ROFL!!!! Hey wait! i just found out there is q1-5 too! lol. TOO! NOT TOOL.

87. anonymous

o lol

88. saifoo.khan

Lmfao. Thank God i don't need glasses.

89. anonymous

yes there is but i did them w/ user @JamesWolf Im lretty sure they are right..

90. anonymous

lol

91. anonymous

o yea like 1

92. anonymous

saifoo, he was struggling to get why we use (n-1) instead of n, so i just let him use n, and told him to call it the 0th term instead of 1st

93. anonymous

so if you can explain it .....

94. anonymous

:)

95. anonymous

because i failed

96. saifoo.khan

0th term.. will give us the first term. o_O

97. saifoo.khan

No wait. it will give us Zero.

98. anonymous

so for the sequence 5,8,11,14 T_n = 5 + (n-1)3

99. saifoo.khan

Yup^

100. anonymous

what does T_n mean???

101. anonymous

but n-1 was confusing so i said to just use n, and let the 1st term "5" be the 0th term

102. anonymous

so T_n = 5 + (0)3

103. saifoo.khan

$\Large T_n = \text{Short for Term Number}$

104. anonymous

oh.

105. anonymous

*tires sigh* so what shall i write?

106. saifoo.khan
107. anonymous

I AM tired lol. I would like to finish this.

108. saifoo.khan

Lol. Where are you stuck exactly?

109. anonymous

On the back. Please just tell me what to write.

110. anonymous

i dont know how to find a term if i do not have a rule

111. saifoo.khan

@JamesWolf to the rescue!

112. anonymous

no, dont do it helpme! you just have to understand it. give a student the answer, and they can get the question right, give a student the method, and they can solve all the questions!

113. saifoo.khan

What do you mean by if you dont have a rule? you have to make a rule of your own.

114. anonymous

Ok

115. anonymous

Thats the thing. Bangs head against wall

133. anonymous
