Based on the calculations, all of the numbers belong to this arithmetic sequence.

<h3>How to calculate an arithmetic sequence?</h3>

Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:

$a_n = a_1 +(n-1)d$

<u>Where:</u>

d is the common difference.

a₁ is the first term of an arithmetic sequence.

n is the total number of terms.

Next, we would determine the common difference as follows:

d = a₂ - a₁

d = 105 - 99 = 6.

d = a₃ - a₂

d = 111 - 105 = 6.

d = a₄ - a₃

d = 117 - 111 = 6.

Based on the calculations, all of the numbers belong to this arithmetic sequence.

I don’t understand this

mylen [45]

To solve for an unknown number, you have to keep isolating it till it is all alone:
A=P(1+rt)
(1+rt)=A/P
rt=A/P -1
r=(A/P-1)/t

dexar [7]

Recall that the formula for the perimeter of a rectangle is: 2Length+2Width
With this in mind, we have that the original design is 96×60, where 90 is length and 60 is width, so it would simply be:
2(96+l) + 2 (60+w) = New Perimeter
Or simplified, it'd be:
2l + 2w + 312 = New Perimeter
