A sequence has a first term of 24 and every other term is one half of the previous term.
Find a recursive formula that defines this sequence.
The answer of this question is:
Somebody can help me and let me know why is 1/2 on the formula? please please!!!
I am not sure if the formula is the right one!!
r = .5
Just as in your other problem, r in a geometric sequence is the ratio of every term to the one before it. That is the very meaning of a geometric sequence.
