Problema Solution

jose has a board that is 5 feet long. he plans to use itto make 4 shelves whose lengths are to be a series of consecutive even numbers. how long should each shelf be in inches?

Answer provided by our tutors

series of consecutive even numbers is 2n-4 , 2n-2 , 2n , 2n+2

from given 

2n-4 , 2n-2 , 2n , 2n+2 = 5

=> 8n-4 = 5

=> n = 9/8

but should be a integer so, he cant make  4 shelves whose lengths are to be a series of consecutive even numbers
