Question

The nth term of a sequence is 3n + 2
work out the first three terms of the sequence

Answer 1

Explanation:

The first three terms are 5,8,11

If the equation for the nth term is 3n+2, we can easily insert numbers into the equation to get the 1st, 2nd, and 3rd term

n=1

3*1+2=5

n=2

3*2+2=8

n=3

3*3+2=11

The first 3 terms are therefore 5,8,11.
