triangular numbers are created when all numbers are added for example: To find the 5 triangular number (1+2+3+4+5).
36 and 45
When you add two consecutive triangular numbers, the result is a perfect square. For example, the first two triangular numbers are 1 (T1) and 3 (T2), and their sum is 4, which is (2^2). In general, the sum of the (n)-th triangular number (T_n) and the ((n+1))-th triangular number (T_{n+1}) equals ((n+1)^2). This relationship holds for all pairs of consecutive triangular numbers.

Triangle numbers or triangular numbers are those numbers that can form an equilateral triangle when counting the objects. The first five triangular numbers are: 1, 3, 6, 10, 15.
There are an many triangular numbers that are also square numbers. Simply put, the sum of two consecutive triangular number equals a square number. Examples include 1 and 36.
24 + 25 + 26 = 75
The numbers are 37, 38, 39 and 40.

Two numbers are consecutive if the second one is the one after the first. Mathematically, if the first number is n then the second is n+1.
The square of the second number.
