I currently have to write half a page about rational exponents, like what they are, and how to solve them, can somebody give me something to copy off of? Each person who answers will get 25 points each

answer: a

step-by-step 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

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
