Find the 7th term of the geometric sequence with a3=125 and r=5

OpenStudy (espex):

So you first need to find the first term (a) and then you can calculate the 7th term. In both cases you will use the formula \(a_n = ar^{(n – 1)}\)

OpenStudy (mathisfun13):

OpenStudy (espex):

That is not the answer I got.

OpenStudy (primeralph):

OpenStudy (mathisfun13):
