N+3=7. To find n, you need to have it by itself, so you can do that by subtracting 3 on both sides, so it would look like: n+3-3=7-3. Then you have n=4.
L+L+(L-4)+(L-4)=72
4L-8=72
4L=80
L= 20
so W= 20-4 or 16
Answer:
Step-by-step explanation:
According to the following pattern sequence (
), it is <u>Arithmetic Sequence</u>, because every negative number is subtracted by 
. So, to find the <u>24th term</u>, you need to use the <u>Arithmetic Sequence Formula</u> and solve to find the 24th term:
: nth term in the sequence
: 1st term
: term position
: Common difference
-Apply to the formula:
-Solve:
Therefore, the 24th term is 
.
Answer:
Yes,
