The common difference between consecutive integers is 1

Recall that integers are sets of whole numbers. If the least of 5 consecutive integers is l, it means that the 5 consecutive integers are

l, l + 1, l + 2, l + 3, l + 4

If the greatest integer is g, then

g = l + 4

Thus,

(l + g)/2 = (l + l + 4)/2 = (2l + 4)/2

Factorising 2 out, we have

2(l + 2)/2

= l + 2

Option C is correct
