rectangular prism with a length, width, and height of 1/5 cm, 2/5 cm, 3/5 and cm, respectively I honestly don't know how to do this PLEASE HELP.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

what is the original number? you forgot to add it.
