Question

Generate the square and triangular pattern with the help of 36 dots​

Answer 1

Answer:

0, 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66… In the above series, each digit represents the number of dots in the triangle. Thus, the square number 36 can be expressed as the sum of the two consecutive triangular numbers 15 and 21. In other words, 15 + 21 = 36.
