15 points the relationship between men’s whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length in inches that corresponds to a shoe size of n. a men’s size 9 fits a foot 10.31 inches long, and a men’s size 13 fits a foot 11.71 inches long. what is the explicit formula for the arithmetic sequence? round to the nearest hundredth, if necessary. a^n= 7.51 + 0.35(n-1) a^n= 9+0.35(n-1) a^n= 9+2.86(n-1) a^n=10.31+2.86(n-1)

Step-by-step explanation:

Formula of nth term =

We are given that  an is the foot length in inches that corresponds to a shoe size of n.

We are given that A men’s size 9 fits a foot 10.31 inches long

So, n = 9

Substitute the values in the formula :

So,

---1

We are given that a men’s size 13 fits a foot 11.71 inches long.

So, n = 13

Substitute the values in the formula :

So,

---2

Subtract 1 form 2

Substitute the value of d in 1

Substitute the value of a and d in formula given above

So, the explicit formula for the arithmetic sequence is

(2,6)
