Question

find the first 3 terms when the nth term is n(n+2)

Answer 1

Answer:

  3, 8, 15

Step-by-step explanation:

Put the numbers 1, 2, and 3 where n is and do the evaluation for each of those values.

  n=1: 1(1+2) = 3

  n=2: 2(2+2) = 8

  n=3: 3(3+2) = 15

The first three terms are 3, 8, 15.
