The sum of two consecutive odd numbers is 100 What is the smaller number

The two numbers can be thought of as: Smaller Odd Number = x + 1 (Add one to ensure it is an odd number) Larger Consecutive Odd Number = Smaller Number + 2 = x + 1 + 2 = x + 3 We know that Smaller Odd Number + Larger Consecutive Odd Number = 100 (X + 1) + (x + 3) = 100 2x + 4 = 100 2x = 96 x = 48 Smaller Odd Number = 48 + 1 = 49 The smaller odd number is 49. The next consecutive odd number of course is 51.
