Question

the sum of 3consecutive odd number is39 find the number

Answer 1

X+X+1+X+2=39
3x+3=39
X+1=13
X=12
therefore the numbers are 12,13,14

Answer 2

Let the three consecutive odd numbers be x, x+2, x+4.
According to the question,
x+x+2+x+4=39
3x+6=39
x+2=13
x=13-2
x=11
Thus, x+2 =11+2=13 and x+4=15
Therefore, three consecutive odd integers whose sum is 39 are 11, 13and 15......
