Question

find the first two numbers that are both triangular and square number

plzz solve with solution

Answer 1

The first two numbers that are both squares and triangles are 1 and 36. 

A square number is a number n where n many pebbles can be arranged in a square. A triangle number is the same, where n number of pebbles can be arranged in a triangle, starting with 1 and then 2, and then 3, and so forth.

generator: a = 3 i = 0
triangle = a + i a = triangle + 3 i += 1 return triangle.

That is simple. I was unable to figure out a way.
so, I was left with generating triangular numbers and then checking for a perfect square

perfect_square(n) rt = sqrt(n) if rt.floor == rt return true else return false.

So my answer to this question is: The above method is a relatively efficient way to find triangular-square numbers. I think that there are an infinite amount of triangular numbers, else they could not be generated using only addition of elements of one infinite set. I can not be sure of there being an infinite number of perfect squares, as I was unable to generate them in a similar manner. 

Hope this helps you friend
