Question

Using the following arithmetic sequence, find the 29th term: –36, –32, –28, –24.

A. 100
B. 64
C. 76
D. 73

Answer 1

using the nth term formular

a+(n-1)d

a = the first term -36
n = the term you are looking for 29
d = common difference 4 (-32 - (-36) = 4

-36 + (29 - 1) 4
-36 + (28 *4)
-36 + (112)
-36 + 112 = 76

C. 76

Answer 2

an=a1+(n-1)d
a29=-36+(28×4)=76
