Let n be a whole number.
Three consecutive even numbers are 2n, 2n+2, 2n+4.


The first and the third numbers are added and this sum is...?
{{{(2n)+(2n+4)}}} = .....?



{{{-22+3(2n+2)}}}, according to the phrase in the description.


The description about the numbers means, {{{highlight(2n+2n+4=-22+3(2n+2))}}}.  
Solve for n and then evaluate each expression for the corresponding numbers.
