12 × ratio = -18
→ ratio = -18/12 = -3/2 = -1.5
Checking:
-18 × ratio = -18 × -3/2 = 27 as required
The common ratio is -3/2 (or -1.5)
The geometric sequence with three terms with a sum of nine and the sum to infinity of 8 is -9,-18, and 36. The first term is -9 and the common ratio is -2.
120 to 180 is an equivalent ratio.
25 is the next number that appears in that sequence.
3/2
3 to 2
The "common ratio" of a geometric series is any of the numbers, divided by the previous number.If in all cases you get the same ratio (the same result of a division), then you have a common ratio. If the division gives you different numbers, then there is no common ratio.
