Find the indicated term of the given arithmetic sequence.

a[1]=45, d=-6, n=8

a. 309

b. - 3

c. 3

d. 87

In order to solve for a nth term in an arithmetic sequence, we use the formula written as:

an = a1 + (n-1) d

where an is the nth term, a1 is the first value in the sequence, n is the term position and d is the common difference.

a8 = 45 + (8-1) - 6

a8 = 45 + (7) (-6)

a8 = 3
