Question

The sequence is geometric. What is the next term?
3125, 625, 125, 25, ....

Answer 1

might want to check to see if each term has a common ratio...

Answer 2

\[\sum_{?}^{?}a^n\]

Answer 3

well backwards if you take your sequence and flip it

Answer 4

\[\sum_{?}^{?}5^n\]

Answer 5

\[\frac{a_{n+1}}{a_n}=\frac{625}{3125}=\frac{125}{625}=\frac{25}{125}=R\]once you know the common ratio R just multiply to find the next term\[a_{n+1}=Ra_n\]
