When the same constant is added to the numbers 60, 100, and 260 a three-term geometric sequence arises. What is the common ratio of the resulting sequence?
[100 + n] / [60 + n] ==[260 + n] / [100 + n], solve for n
n== - 46 2/3 - this is the constant.
Your 3-term GP will look like this:
40/3, 160/3, 640/3
[160/3] / [40/3]==4 - this is the common ratio.
