There are four answer choices
Sum of n terms = a1 r^n - 1 ------- r - 1 whre a1 = first term and r = common ratio
so plug in a1 = 8 , r = -6 and n = 7
sorry a1 = -3
So it's -3(-6)^7-1 over -6-1?
not exactly - work out the (-6)^7 first then subtract 1 then divide by -7 finally multiply by -3
I got -119,973 is that right?
I should have written the (r^n - 1) like that - in parentheses
yes
Okay thank you very much
