Question

Find an equation for the nth term of the arithmetic sequence. (7 points)

a15 = -53, a16 = -5


an = -725 - 48(n - 1)
an = -725 + 48(n + 1)
an = -725 + 48(n - 1)
an = -725 - 48(n + 1)

Answer 4

your original equation is A(N)=a+(n-1)d
A(N)-value of the nth term
a-first value
n-number of the nth term
d-common difference.

Plug what they give you in for the symbol
