Question

A(n)=−6−4(n−1)
Find the 4th term in the sequence

Answer 1

The 4th term is -18.

Explanation:

This is an explicit formula.

All we have to do is plug n = 4 in the formula to find the 4th term
a (4) = -6 - 4 (4 - 1)
= -18

Answer 2

If n = the term number, then:
A(4) = 6-4(4-1)
A(4) = 6-4(3)
A(4) = 6-12
A(4) = -6
A = -1.5
