Questions. the sum of three consecutive odd number is 21 .Find the number.
Answer.
(FIRST I Tell about consecutive number.)
Consecutive numbers are numbers that follow each other in order. They have a difference of 1 between every two numbers. In a set of consecutive numbers,the mean and the median are Equal. If n is a number, then n, n+1, and n+2 .

Now ➢


odd consecutive number.
Consecutive Odd Numbers. If x is any odd number, then x and x + 2 are consecutive odd numbers. E.g. 7 and 9 are consecutive odd numbers, as are 31 and 33.



so ............
now go on question
let x be an odd number
therefore.let three consecutive number are

x,x+2,x+4

so there sum will be
x+x+2+x+4=21
3x+6=21
3x=21-6
3x=15
x=5
so three consecutive number will be
x,x+2,x+4
5,5+2,5+4,
5,7,9
hence and is 5,7,9
