whatever @CliffSedge is writing, just know that i give him/her a medal :P

3. CliffSedge

Ok, first look to see how each term follows from the previous one. e.g. 1) -7, -10, -13, -16, ... It seems like each term is 3 less than the one that came before it, so follow that pattern.

4. helpmeplz311

Which problem do youn eed help with?

24. helpmeplz311

number 9

25. helpmeplz311

the odds.

26. saifoo.khan

Solve step by step: Let's insert 1 first. y = 3(1) - 1 y = 2 So first term = 2 Insert 2. y = 3(2) -1 y = 5 And so on..

27. helpmeplz311

um it says which one fit the sequence

28. saifoo.khan

Yes.. so we are going to try insert the values 1,2, 3, 4 and so on..

29. helpmeplz311

Ok ill try. i do not get jt

30. saifoo.khan

Why? Where are you stuck?

31. helpmeplz311

Well, you want me to insert the numbers in each answer choice into the equation

32. saifoo.khan

No. Okay. Let me explain you again. Forget everything now

33. helpmeplz311

okay

34. saifoo.khan

Step 1: Forget that you are given any options. Step 2: You are given an equation. y = 3n -1 Where the value of indicates the term number.. 1, 2, 3, and so on..

35. helpmeplz311

yes

36. saifoo.khan

Alright, so now: y = 3n - 1 Find the first term: y = 3(1) - 1 y = 2 So first term = 2 ---------------------- Find 2nd term Insert 2. y = 3(2) -1 y = 5 Now find 3rd term

37. helpmeplz311

the thirdnterm would be 8?

38. saifoo.khan
