Question

11. The sum of three consecutivo de numbers is 21 Find the numbers.​

Answer 1

Answer:

Step-by-step explanation:

hello

Let the three consecutive odd number be x,x + 2,x + 4.

Given that the sum of 3 consecutive odd numbers is 21.

x + x + 2 + x + 4 = 21

3x + 6 = 21

3x = 21 - 6

3x = 15

x = 15/3

x = 5.

x + 2 = 5 + 2

        = 7

x + 4 = 5 + 4

        = 9.

Therefore the numbers are 5,7,9.

Verification:

5 + 7 + 9 = 21

21 = 21.

Hope this helps!
