Answer:
Step-by-step explanation:
The explicit form for an arithmetic sequence is:
where is the first term and [ted]d[/tex] is the common difference.
The given sequence is arithmetic because term-previous term is the same per each pair of term and previous term.
That is the following holds:
-4-3=-11-(-4)=-18-(-11)
All of these differences are equal to -7, the common difference.
So let's fill in the explicit form:

Answer:
4%
Step-by-step explanation:
A = final amount
P = initial amount
r = interest rate per time period
n = number of times compounded per time period
t = number of time period
A = 3932.82
r = what we want to find
n = 2
t = 6
divide both sides by 3101 to isolate the exponent and its parts
put both sides to the power of (1/12) to help isolate the variable
subtract 1 from both sides to isolate the variable and its coefficient
multiply both sides by 2 to get r
r ≈ 0.04 = 4%
