Dear Customer
Welcome, and thank you for trusting us
______+______+_____=30 1 3 5 7 9 11 13 15 Fill in the blanket
The odd number can be written in the form 2 n +1 (n is an integer)
so when we sum three odd numbers
let the first number = 2 x+1
the second number =2 y +1
the third number=2 z+1
the sum of three odd numbers=
2x+1+2 y+1+ 2z+1=
2x+2y+2z+1+1+1=
=2(x+y+z)+3
=2(x+y+z+1) +1
= 2m+1
and this is an odd number
so the sum of three odd number can not be an even number
so the sum of three odd number can not be equal 30
because 30 is an even number
