Arithmetic sequence(examples of it plzzz!)

I have attached an example of an arithmetic sequence below.

This specific sequence involves decimals.

Notice that to get from one term to the next, we add

1.3 each time in order to reach the next term.

In order for a sequence to be arithmetic, the difference between the terms in the sequence must remain constant at all times.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
