Question

- The sum of three consecutive odd numbers
is 57. Find the numbers.
​

Answer 1

Answer:

Let the 3 consecutive odd nos be x,x+2,x+4

x+x+2+x+4=57

3x=51

x=17

So the nos are 17,19 and 21.

Answer 2

Let the three consecutive odd numbers be x, (x+2), (x-2)

.

x + ( x + 2 ) + ( x - 2) = 57

x + x + 2 + x - 2 = 57

3x = 57

x = 57/3

x = 19

x + 2 = 19 + 2 = 21

x - 2 = 19 - 2 = 17

>> The three numbers are 19, 17, 21.
