Question 1104433: Consider a geometric sequence where the first term is 768 and the second term is 576.
Find the least value of n such that the nth term of the sequence is less than 7
Do we do 576-768 to find r, then use an equation to find the nth term?

.
It is  GEOMETRIC  progression.

To find  "r",  you must use the ratio  576%2F768 = 3%2F4 = 0.75.


The difference  576-768  you are talking about is  IRRELEVANT.
