Question

If the sum of three consecutive odd numbers is 81, find the largest odd number

Answer 1

Step-by-step explanation:

Let Smallest number be 'x'

and Largest number be 'x+4'

Let 3 consecutive odd numbers be x, x+2, x+4

As per the question,

x+x+2+x+4 = 81

3x + 6 = 81

3× = 81-6 = 75

x = 25

Therefore, Largest number = x+4 = 25+4 = 29
