For this equation I'm supposed to find the first term and the sum of the geometric sequence.
an = 24, r = 2/3, n = 4
For this one I need to find the first and last term of the sequence given the information below.
Sn = 1022, r =2, n = 9
I know that the formulas for geometric series are:
Sn=(a1-a1r^n)/1-r & Sn=(a1-ran)/1-r
Im not sure how to solve these though. My book doesn't show how to do these probelms.
