Answer:
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
The answer is supplementary angles, hopefully that helps.
