Answer:
b. 
Step-by-step explanation:

Switch sides.

Subtract 14j from both sides.

Divide both sides by 3.

First term = (2)5^(-2*1) =2/25
2nd term = (2)5^(-2*2) = 2/ 625
3rd term = 2(5)^(-2*3) = 2/ 15625
If we divide the 3rd term by the 2nd term or the 2nd term by the first we get the common ratio
Common ratio = 1/25 or 0.04 as a decimal fraction.
Answer:
No
Step-by-step explanation:
49 ≥ 10d
49 ≥ 10(8)
49 ≥ 80
49 has to be greater than or equal to 80
d = 8 isn’t a solution
