Question

The sum of three consecutive odd numbers is 27 .Find the largest number.​

Answer 1

Answer:

the greatest of the 3 consecutive odd numbers is 15

Step-by-step explanation:

let the 3 consecutive odd numbers be 2n-1 , 2n+1, and 2n+3

given, sum of 3 consecutive odd numbers = 27

=> 2n-1 + 2n+1 + 2n+3 = 27

=> 6n+3 = 27

=> 6n = 27-3  = 24

=> n  = 24/6

=> n=6

therefore the no.s are , 2(6)-1 , 2(6)+1 , and 2(6)+3

                             =>        12-1, 12+1, 12+3

                             => 11,13,15

the greatest of the numbers is 15
