31. D

32. B

33. A

34. D This is an arithmetic sequence with common difference of 4. The first element is 2, and total elements are 12. So, a₁ = 1, d = 3 and n = 12. So, by using the formula of nth term of an arithmetic sequence, first we will find the 12th term

Now, by using the formula for the sum of n elements of an arithmetic sequence, we have

35. D
