Given:
A number, 72.
To Find:
72 as a sum of odd numbers.
Solution:
An odd number is a number that is not a multiple of 2. We cannot divide odd numbers into an exact pair. The general form of odd numbers is 2m+1.
Now 72 can be written as a sum of odd numbers in multiple ways. Some of the ways are given below:
(i) 72 = 71 + 1
(ii) 72 = 69 + 3
(iii) 72 = 67 + 5
(iv) 72 = 65 + 7
(v) 72 = 63 + 9
(vi) 72 = 61 + 11
(vii) 72 = 51 + 21
(viii) 72 = 41 + 31
(ix) 72 = 53 + 19
(x) 72 = 43 + 29.
∴ 72 can be written as a sum of odd numbers in the following ways:
71 + 1, 69 + 3, 67 + 5,..etc.
