Find the nth term of each arithmetic sequence.
f(1) = -1, d=-10, n=25
f(1) = -3, d=-9, n=11
f(1) = -7, d = 3, n=17
f(1) = 2, d = 1/2, n=8

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9
