Answer:

Step-by-step explanation:
Recursive Sequence
We are given the following sequence:
-1, 1, 5, 13...
It's required to find the recursive term for the sequence.
A recursive formula calculates each term as a function of one or more previous terms.
To find the recursive formula, we must find a pattern and transform it into a math expression.
Let's write the sequence, and below it, the difference of consecutive terms:
-1, 1, 5, 13...
+2, +4, +8
Note the difference between consecutive terms is always a power of 2, starting from 2^1, 2^2, 2^3.
The exponent is one less than the number of the term, thus:

Thus:

Testing:
n=1
(given).
n=2

n=3

n=4

T= Total cost
m= # of members
Total equals $60 fee plus ($15 times # of members) plus $95 fee plus ($12 times # of members)
T= $60 + $15m + $95 + $12m
combine like terms
EXPRESSION:
T= $27m + $155

The annual Social Security benefit is 42% of $50,760. 42% of $50,760 is $21,319.20. So Bob will receive $21,319.20 from his annual Social Security benefit.
Answer:
the ratio is 5 to 1.
Step-by-step explanation:
Answer: Yes, they can.
Clarification:
We have three different sides with different lengths:
These three lengths can form a triangle, an isosceles triangle.
Isosceles triangles have three different side lengths.
Hope this helps you. Best of Luck!
