Answer:
Step-by-step explanation:
common ratio=18/-3=-108/18=-6, a=-3
sn=a(r^n-1)(r-1)
sn=-3((-6)^n-1)(-6-1)
sn=-3(-6)^8-1)/(-7)
s8=-3(1679615)/(-7)
s8=719836
90.42857143 or
90.4 to nearest decimal
His new balance will be $805.8915

1. 3+2+1+2+3+1=12
2. 5+6+6+7+6+6=36
3. 2+4+3+3+2+4=18
Then add all those numbers up and divide them by 18.
12+36+18=66/18=3.6 you can round it up to c.4.
