using the formula for the sum of the first n terms of a geometric sequence, what is the sum of the first 12 terms? carry all calculations to 6 decimals.
Thank you
Math question 3 c?
whats the series?
tell start term and common ratio
Reply:your question is incomplete!
by the way, the formula to solve the question is
[ a ( r^n - 1) ] / [ r - 1 ]
where 'a' is the first term and 'r' is the common ratio.
If it's fraction numbers, the sum to infinity would be
a / [ 1 - r ]
