If are three consecutive terms in a geometric sequence,
determine the numerical value(s) of the common ratio(s).
Correct answer is -1 and 3 . These are values of
but if you plug that back in the -1 works
. . but the 3 gives you 1, 7, 17? . You're letting
I did 5x +2 over x+4 equal to x+4 over x-2
solved for x by factoring and got -1,5 . . . . correct so far!
and my ratios are -1 and 5 when I plug them back in. . . . . How?
