What is an Arithmetic Sequence or an Arithmetic Progression?
Arithmetic Sequence is a sequence in which difference between any two consecutive terms is constant.
For example, we have sequence: 5, 8, 11, 14, 17, 20, 23.
The difference between any two consecutive terms is 3.
A natural number m is called a perfect square number if it can be expressed as
where n is also a natural number. For example, 4 is a perfect square number because it is a natural number and it can be expressed as
and 2 is also a natural number.
