Find the 25th term of the arithmetic sequence when a1 = - 14 and d = - 5

a25 = - 134

Step-by-step explanation:

For first term a1 and common difference d, the formula for the n-th term is ...

an = a1 + d (n - 1)

You want to evaluate this for n=25, a1=-14, d=-5. Filling in the numbers and doing the arithmetic, you get ...

a25 = - 14 - 5 (25 - 1) = - 14 - 120

a25 = - 134
