Question

A sequence has an explicit rule f(n)=6 - n^2. find the first 3 terms.
help pretty pleaseeee

Answer 1

5, 2, - 3

Explanation:

To find the first 3 terms substitute n = 1, 2, 3 into the explicit rule, that is

f(1) = 6 - 1² = 6 - 1 = 5

f(2) = 6 - 2² = 6 - 4 = 2

f(3) = 6 - 3² = 6 - 9 = - 3

The first 3 terms are 5, 2, - 3
