Jeremy can determine the total number of miles walked at a constant speed by using the formula an=an-1+3 if a1=2, what are the first three terms of the sequence?

A. 2,5,8

B. 2,6,18

C. 2,-1,-4

D. 2,4,6

If the recursive formula is a (n) = a (n-1) + 3 and a1=2 then the explicit formula is:

a (n) = 2+3 (n-1) which simplifies to

a (n) = 2+3n-3

a (n) = 3n-1 so the first three terms are a (1), a (2), and a (3) which are:

2, 5, and 8
