Question

ALG. 2

What is the sum of a 6–term geometric series if the first term is 24 and the last term is 1,417,176?

I know this is geometric series, but I do not remember how to get the answer to this kind where you have to find the ratio without having a sequence of numbers....

Answer 1

here common ratio r = \[\sqrt[5]{1417176/24}\] =9

Answer 2

thanks!
