Answer:
Explanation:
Solution :-
A series of whole numbers that follow one another consecutively and without any breaks are known as consecutive natural numbers. To put it another way, when you list a series of natural numbers, each one is one unit bigger than the one before it. Natural numbers are ordered starting at 1, and each additional number is created by adding 1 to the previous number.
The initial few consecutive natural numbers, for instance, are:
1, 2, 3, 4, 5, 6, ...
(a) 49:
25² - 24²=625-576=49
(b) 75:
19² - 18²=361-324=75
(c) 125:
63² - 62²=3969-3844
