Question

The sum of three concecutive odd numbers is 21. find the numbers

Answer 1

Hey

Let one number be x.
Then, the other number will be x+2.
The third number = x+2+2 = x +4


It is given that their sum is 21.

So, 
x + (x+2) + (x+4) = 21
= 3x + 6 = 21
= 3x = 15
x = 5
and x+2 = 7
x+4 = 9.

Hence, the three consecutive odd numbers whose sum is 21 are 5, 7 and 9.

hello users .....

we have given that 
The sum of three concecutive odd numbers is 21

we have to find these odd numbers 

solution :-

let the first number be = x 
because these odd  numbers are consecutive 
then
2nd number be = (x+2) 
3rd number be = (x+4)

according to question 

x + (x+2) + (x+4) = 21
=> 3x +6 = 21 
=> 3x = 21 - 6 = 15
=> x = 5 



hence;

the first number = 5 
second number = 5+2 = 7 
third number = 5+4 = 9 answer
