The relationship between women'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 a n. A women's size 7 fits a foot 9 1/3 inches long, ands women's size 12 fits a foot 11 inches long. What is the explicit formula for the arithmetic sequence? Round to the nearest hundredth, if necessary. an=-17.91 +2.99(n-1), an=-5+2.99(n-1), an=7+0.33(n-1) , an=7.35+ 0.33(n-1)
The relationship between women'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.
We are given values for n=7 and n=12 as a7=9.33 and a12=11
So, we proceed from the options and check which an satisfies these values:
