Find the 8th term of the sequence described by the explicit formula.

Question

an = 5 - 3 ( n - 1)

A. -16
B. 5
C. -3
D. 8

Answer 1

To find the 8th term of the sequence, we substitute n = 8 into the given explicit formula:

a8 = 5 - 3(8 - 1)
= 5 - 3(7)
= 5 - 21
= -16

Therefore, the 8th term of the sequence is -16, which corresponds to option A.
