Create a function which takes in a number as a parameter and returns whether it is a square number

Examples:

isSquare(1) returns true

isSquare(64) returns true

isSquare(65) returns false

Extension:

Output the first 100 square numbers

Also output the 'jump' between consecutive squares - for example, the squares 0, 1, 4 would have a jump of 1, 3 - is there a pattern? If so, is there a formula you can think of to represent this?
