Question

The sum of three consecutive odd numbers is 51. Find the numbers

Answer 1

Answer- Let no. be x, x+2 and x+4
Now, x+x+2+x+4= 51
3x+6= 51
3x= 51-6
3x= 45
x= 45/3
Therefore, x= 15
x+2 = 15+2= 17
x+4 = 15+4= 19

Answer 2

let the three no.s be x,x+2,x+4 so,x+(x+2)+(x+4)=51
so,3x+6=51
3x=51-6=45
3x=45
x=45/3
=15
So, the three no.s are-
x=15
x+2=17
x+4=19
verification-
15+17+19=51
ans-so,the 3no.s are-
15,17,19
