Answer:
-18
Step-by-step explanation:
The answer is -18 because a negative plus a positive is always a negative.
I guess you are asking to find the sum of the first 8 terms. If so, then:
Sum = a₁(1-rⁿ)/(1-r), where a₁ is the 1st term, r=common ratio and n=number of terms:
the 1st term a₁ =3
common ratio r = - 2 (since -6/3 = - 2, and 12/-6 = - 2, etc.)
Sum = 3[(1- (-2)⁸]/(1-2) = 3(1- 256)/(1/2)
Sum = -1530
I think that the answer would be 5/5
15 3/4% = 15.75%
15.75% = 0.1575
The answer is A.
