Determine if the sequence is geometric. If it is, find the term named in the problem.

1 answer:

4 0

Answer:

120

Step-by-step explanation:

Each new term is twice the previous term, so this is a geometric sequence. The applicable formula is

a(n) = a(1)*4*(n - 1)

and so a(9) = 4*4(9 - 1) = 120

An= A1 + d(n-1)
An= 170 + (-85)(n-1)
An=170-85(n-1)
An= 170-85n+85
