Let the 3 consecutive odd numbers be 'x' , x + 2 and x + 4
So,
x + x + 2 + x + 4 = 165
3x + 6 = 165
3x = 159
x = 53
The numbers are 53 , 55, 57
Hope This Helps You!

Lets keep the three numbers as x, y and z. But we need odd numbers, so lets keep it as x, x=2, and x=4.
So,
⇒x+(x+2)+(x+4)=165
⇒x3+6= 165
⇒x3= 165-6
= 159
⇒x3= 159
⇒x= 159/3
= 53
⇒x= 53
⇒x+2= 53=2=55 →x+2=55
⇒x+4+53+4=57 →x+4=57
So, the three odd integers are 53,55 and 57.

but it is not a n odd no.
Why ?
thay all are odd and consecutive...
anyways, thanks!!
odd no. is 1,3,5 etc.
numbers ending with 1,3,5,7 and 9 are odd numbers
but no. we let is 2,4 and it is not an odd no.
no.........thats even................numbers ending with 2,4,6,8, and 0 are even numbers
ya ilm try to say that. in que u take x ,x+2,x+4 and this no. is even. but acc. to que we want three cinsecutive odd no.
that is so that we can find the numbers, even the other person has used the same method. u better ask her @BellaStark1
