sum of three consecutive odd integers is 51. find the numbers
dhruvparikh:
18,19 and 20
see it
x+(x+1)+(x+2)=51
3x=48
x=16
16,17,18
3x=48
x=16
16,17,18
How 18,19 and 20?
is my answer correct neelabh
the nos must be odd

let's take the numbers as x , x +2, and x+4
so x+x+2+x+4=51
3x+6=51
3x=51-6=45
=x=45/3=15
hence the now are 15,15+2=17 and 15+4=19
hope this helps

Let us take one number as x.
Difference between two odd numbers = 2 (3 - 1 = 2, 7 - 5 = 2,....)
Therefore the numbers will be x, x + 2 and x + 4.
x + x + 2 + x + 4 = 51
3x + 6 = 51
3x = 51 - 6
3x = 45
x = 45/3
x = 15
Therefore the numbers are x = 15, x + 2 = 15 + 2 = 17 and x + 4 = 15 + 4 = 19
Hope it helps :)
