Question

The sum of three consecutive odd numbers is 63.find the numbers

Answer 1

let the no. be x , 1+x and 1+1+x.
according to question.,,
=x+1+x+1+x+1+1=63
=3x +4= 63
=3x =63-4
=x=59÷3

=x=19.66 (not approx)
1st no. is x = 19.66
2nd no. is x+1 = 19.66+1= 20.66
3rd no. is x+1+1 = 19.66+1+1=21.66

Answer 2

Answer:

19, 21 and 23

Step-by-step explanation:

We know that consecutive odd number differ by 2 so,

Let the three consecutive odd numbers be x, ( x + 2 ) and ( x + 4 ) respectively.

We can derive the following equation by reading the question carefully,

x + ( x + 2 ) + ( x + 4 ) = 63

x + x + 2 + x + 4 = 63

3x + 6 = 63

3x = 63 - 6

3x = 57

x = 57 / 3

x = 19

Therefore we can calculate the consecutive odd numbers now:

First Consecutive Odd Number = 19

Second Consecutive Odd Number = 19 + 2 = 21

Third Consecutive Odd Number = 19 + 4 = 23
