Step-by-step explanation:

First, note that this is a geometric sequence. This is because each term is 2 times its previous term.

The standard recursive form for a geometric sequence is:

Where n is the nth term, so n-1 is the previous term, and r is the common ratio.

Substitute 2 for r.

Therefore, our recursive formula is:

The standard form of the explicit formula for geometric sequences is:

Again, r is the common ratio and a is the initial term.

The common ratio is 2 and the initial term is 2. So, substitute:

And that's our explicit formula.

And we're done!

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
