Question
Write the first five terms of the geometric sequence if its first term is $-64, r>0,$ and its fifth term is $-4$.
Step 1
We can use the formula for the nth term of a geometric sequence, which is $a_n = a_1 \cdot r^{(n-1)}$, where $a_n$ is the nth term, $a_1$ is the first term, $r$ is the common ratio, and $n$ is the term number. Show more…
