If x - 2 , x + 4 , 5x + 2 are three consecutive terms in a geometric sequence, determine the numerical value(s) of the common ratio(s).

answer correct answer is -1 and 3

but if you plug that back in the -1 works but the 3 gives you

1,7,17?

I did 5x +2 over x+4 equal to x+4 over x-2

cross multilpied

solved for x by factoring and got -1,5 and my ratios are -1 and 5 when I plug them back in.... whats goin on?
