Answer: No, the equation is not accurate.
Step-by-step explanation: The proper equation is 4x + 40 = 129. This is because 16 is nowhere in the scenario, and the term before x is months, so the correct term would be 4x.
For starters,
Consider the 
th partial sum, denoted by 
:
Multiply both sides by 
:
Subtract from this:
Solve for :
Now as 
, the exponential term will converge to 0, since 
if 
. This leaves us with
Answer:
log(6) = x
Step-by-step explanation:
4log(216)=12x
Divide both sides by 12
log(216)/3 = x
Use properties of logs
log(216^(1/3)) = x
Simplify
log(6) = x
Answer:
