No.
an integer is a whole number like 1,2,3 etc

No, the square root of an integer will not always be an integer. It may or may not be. The square root of nine is three, both of which are integers. The square root of two is not an integer. In fact, it is not even a rational number.

0.75*(2n+1) where n is an integer.
It is 2/1 which is, in fact, an integer.
it equals six over nine or two over three
The sum of three consecutive integers is -72
