Answer:
The rule for given sequence is: a_n = -27+16n
And the 100th term is: 1573
Step-by-step explanation:
Given sequence is:
-11, 5, 21, 37, 53, ...
Here

First of all, we have to find if this is an arithmetic sequence
For that purpose, the common difference has to be found. Common difference, denoted by d, is the difference between consecutive terms of an arithmetic sequence
So,

As the common difference is same, the sequence is an arithmetic sequence
General rule for arithmetic sequence is:

Putting values

For 100th term,
Putting n=100

Hence,
The rule for given sequence is: a_n = -27+16n
And the 100th term is: 1573
Answer:
84ft
Step-by-step explanation:
The formula to find the area of a parallelogram is b x h.
The base is 14ft and the height is 6ft. Multiply these together.
14 x 6 = 84ft

Collecting like terms,

Since the signs change when its position changes.
