Find the recursive formula -80, 20, -5

= -

Step-by-step explanation:

The recursive formula lets us find a term in the sequence by multiplying the previous term by the common ratio r

Here r = = = -

Then recursive formula is

= -

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

1/3 + 1/5 = 8/15.

step-by-step explanation:
