Question

the sum of three consecutive odd number is 129 find the biggest number

Answer 1

let the three consecutive numbers be x, X + 2, X + 4
as their sum is 129 we conclude
x+x+2+x+4=129
3x+6=129
3x=129-6
3x=123
therefore x=123/3
x=41
this is the answer

Answer 2

Solution :-

Let,
The first odd integer be:x

Then the second odd integer is:-
x+2

Then the third odd integer is:-
x+2+2=x+4

Sum of three consecutive odd numbers = 129

A/q

(x)+(x+2)+(x+4)= 129
3x+6= 129
3x= 129-6
3x= 123
x= 41
now

The first integer is: x= 41

The second integer is: x+2=19+2 = 43

The third integer is: x+4=19+4= 45

Biggest number is 45
