The sum of first n odd natural numbers can be calculated as n2, where n is the number of odd natural.
For example,
Sum = 1 + 3 + 5 + 7; number of odd natural = 4
Therefore, Sum = 42 = 16
Write a program to input number of odd natural terms and display sum of the given series:
(a) 1 + 3 + 5 + ………………. + 29 + 31
(b) 1 + 3 + 5 + 7 + ………………. + 47 + 49
