Question

the sum of three consecutive odd number is 51 find the numbers

Answer 1

Let the first consecutive odd number be x+1
And second be x+3
Ans third one be x+5
A/q
$= x + 1 + x + 3 + x + 5 = 51 \\ 3x + 9 = 51 \\ 3x = 51 - 9 \\ 3x = 42$
$x = \frac{42}{3} = 14$
So,first consecutive odd number=14+1=15
Second one=14+3=17
Third =14+5=19

Answer 2

Let the odd no is x
So
The three consecutive odd is
x+1,x+3,x+5
Now,
x+1,x+3,x+5
x+1+x+3+x+5=51
Now we add
3x+9=51
3x=51-9
3x=42
x=42/3
x=14
x+1=14+1=15
x+3=14+3=17
x+5=14+5=19
Hope it helps
