Any number that has 4 or 6 in its unit’s place, its square will always end with 6.

Any number that has zero as its unit place, the square of that number will always have an even number of zeros at the end.
2. Some More Interesting Patterns

Adding triangular numbers  If the dotted pattern can be arranged in a triangular shape, then the numbers are referred to as triangular numbers. If we add two consecutive triangular numbers, we get a square number.

Numbers between square numbers  If we have two consecutive numbers n and n + 1, then there are (2n) non perfect square numbers between their square numbers.

Adding odd numbers  The sum of the first n natural odd numbers is n^{2}.
Any square number must be the sum of consecutive odd numbers starting from 1. if any natural number which is not a sum of successive odd natural numbers starting with 1, then it will not be a perfect square.

A sum of consecutive natural numbers  Every square number is the summation of two consecutive positive natural numbers. For example, if you are finding the square of n to identify two consecutive natural numbers, you can utilize the formula:
First number = n^{2}1/2
Second number = n^{2}+1/2

Product of two consecutive even or odd natural numbers  If we have two consecutive even or odd numbers (a+1) and a 1, the product will be (a21).
