Question

Find the next three terms of the sequence. Then write a rule for the sequence.

648, 216, 72, 24

Write the geometric sequence as a function.
Use an explicit formula

Answer 1

The common ratio is \({1 \over 3}\), so you will multiply by 1 over 3 to get the next term in the sequence.

Answer 2

\(\Large \color{MidnightBlue}{\Rightarrow g_{n} = 1944 * ({1 \over 3})^n }\)

Answer 3

what is the 1944 part?

Answer 4

I've basically simplified this.

Answer 5

It was originally:

\(\Large \color{MidnightBlue}{\Rightarrow 648 * ({1 \over 3})^{n - 1} }\)
