The perimeter of a rectangular field is 344 yards. If the width of the field is 79 yards, what is it’s length

93 yards

Step-by-step explanation:

When you have a rectanglular field, you can double the width, and then double the length, then add them together to get the perimeter.

If the perimeter is 344, and the width is 79, we can double it to find the value of 2 of the sides, because, if you are on a rectangular field, double the width, then you have to add it to the lengt doubled.

79+79=158

We can subtract 344 by 158 to get the doubled version of the length. After we find the doubled version of the length, we have to divide that by 2.

344-158=186

Now, like I said, we have to divide 186 by 2 to find how much the length is.

186/2=93

The length is 93 yards.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
