Question

The first five terms of a pattern are given below. 38, 41, 44, 47, 50.... Which expression can be used to determine the nth term of the pattern? A. 35 + 3n B. 41 - 3n C. 40 - 2n D. 36 + 2n

Answer 1

A

Explanation:

a = 38

d = 41 - 38 = 3

nth term = 38 + 3(n-1)

= 38 + 3n - 3

= 35 + 3n
