id like some help with these questions please
1) If x-3, x-1, and 4x-2 are consecutive terms in a geometric sequence, find x
Answers are 1/3 and 5, I can solve for 1/3 but not 5, I must be solving the wrong way
2) The sum of the first 2 terms of a geometric sequence is 3. The sum of the next 2 terms is 4/3. Find the first 4 terms
Answers are 9/5, 6/5, 4/5, 8/15 or 9. -6, 4, -8/3
these are giving me trouble, thanks
