Question

How do I find the fifth term of a geometric sequence on a calculator?

Answer 1

A geometric sequence is a sequence of the form
`a, ar, ar^2, ar^3, ...`
where `a` is an initial value and `r` is a common ratio between terms.

Note that the first term of the sequence is `ar^0`
so the `n`th term of the sequence is `ar^(n-1)`

Thus, in order to find the fifth term, assuming prior knowledge of `a` and `r`, simply plug in `a*r^4`.
