Answer:
A an = -3 * (1/8) ^ (n-1)
Step-by-step explanation:
We know the first term a1 = -3
And the common ratio r = 1/8 from the an = an-1 * 1/8
The explicit formula is
an = a1 r^ (n-1)
an = -3 * (1/8) ^ (n-1)
Answer:
A
Step-by-step explanation:
a₁ = -3 ------> first term
r ----> common ratio

(25000-f)(.03)+.05f=1100
750-.03f+.05f=1100
750+.02f=1100
.02f=350
f=$17500
So Mary invested $17500 @ 5% and 7500 at 3% to earn $1100 in interest.
