Class 8 Mathematics Chapter 1 A Square and A Cube solutions
The 36th odd number can be found using the formula for the nth odd number, which is 2n – 1. So, 2 × 36 = 72 and subtracting 1 gives 71. Thus, the 36th odd number is 71. This method is useful when calculating squares by summing consecutive odd numbers, like 1 + 3 + 5 + … + 71 to get the square of 36, which is 1296.
