25. helpmeplz311

*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. helpmeplz311

:( okay

32. saifoo.khan

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

33. helpmeplz311

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

34. helpmeplz311

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. helpmeplz311

ok,thanks

38. helpmeplz311

39. saifoo.khan

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

40. helpmeplz311

ok.

41. helpmeplz311

saifoo?

42. saifoo.khan

Back!

43. helpmeplz311

o ok:)

44. saifoo.khan

So?

45. helpmeplz311

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. helpmeplz311

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. helpmeplz311

lol yay!!

51. helpmeplz311

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. helpmeplz311

Okay.

54. helpmeplz311

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. helpmeplz311

ook.

58. saifoo.khan

59. helpmeplz311

let me try no.1

60. helpmeplz311

lol

61. saifoo.khan

Sure.

62. saifoo.khan

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

63. helpmeplz311

ok. 10+(70-1)8

64. saifoo.khan

Wow, nice.

65. helpmeplz311

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

66. saifoo.khan

Haha. :/

67. helpmeplz311

: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. helpmeplz311

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. helpmeplz311

81. helpmeplz311

lol,scroll up..12 mins ago..

82. helpmeplz311

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. helpmeplz311

'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. helpmeplz311

o lol

88. saifoo.khan

Lmfao. Thank God i don't need glasses.

89. helpmeplz311

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

90. helpmeplz311

lol

91. helpmeplz311

o yea like 1

92. JamesWolf

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. JamesWolf

so if you can explain it .....

94. JamesWolf

:)

95. JamesWolf

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. JamesWolf

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

99. saifoo.khan

Yup^

100. helpmeplz311

what does T_n mean???

101. JamesWolf

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

102. JamesWolf

so T_n = 5 + (0)3

103. saifoo.khan

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

104. helpmeplz311

oh.

105. helpmeplz311

*tires sigh* so what shall i write?

106. saifoo.khan
107. helpmeplz311

108. saifoo.khan

Lol. Where are you stuck exactly?

109. helpmeplz311

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

110. helpmeplz311

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

111. saifoo.khan

@JamesWolf to the rescue!

112. JamesWolf

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. helpmeplz311

Ok

115. helpmeplz311
