MATHEMATICS SHORT TRICKS FOR Numerology Problems Part 1

                   Natural numbers
                                    

Sum of natural numbers = n (n + 1) / 2

The sum of the classes of natural numbers = n (n + 1) (2n + 1) / 6

The sum of the times of natural numbers = n² (n + 1) ² / 4

Natural three consecutive numbers = x, x + 1, x + 2

          Even number           

Sum of equals = n (n + 2) / 4

Sum of classes of even numbers

                                     = 4 (n / 2 (n / 2 + 1) (n + 1) / 6

Even three consecutive numbers = x, x + 2, x + 4

      odd number

Sum of odd numbers = (n + 1/2) ²

          Prime number

          Who does not cut off any of his

         Example - 2, 3, 5, 7, 11 --------

Question 1 - In the three numbers, the ratio of 2: 3: 5 is that the sum of their classes is 152, then what is the sum of those numbers?

Solve - Addition of Classes

        ⁽2x⁾² + ⁽3X⁾² + ⁽5X⁾² = 152

                       38x² = 152

                          X² = 152/38

                          X² = 4

                           X = 2

So obtained number 2x = 4

                      3x = 6

                      5X = 10

              Total = 4 + 6 + 10 = 20 ans
