Add five odd number which equals 50?

Answer 1

1+3+5+5+17+19 = 50

these are six numbers that make 50, but if u look closely, one number(5) is repeated

which means the total distinct odd numbers in this answer are 5.

No other solution to my knowledge

It is not possible for five odd numbers to add up to 50 or any even number. All even numbers have the form 2x, where x is an integer, that is if you divide an even number by two you get an integer.

All odd numbers have the form 2x + 1, where x is an integer. Another way of looking at this is that every odd number is an even number plus 1.

So lets take five odd numbers, 2v+1, 2w+1, 2x+1, 2y+1, and 2z+1, where v, w, x, y, and z are distinct integers. Adding them together we get:

(2v+1) + (2w+1) + (2x+1) + (2y+1) + (2z+1)

2v + 2w + 2x + 2y + 2z + 5

2v + 2w + 2x + 2y + 2z + 4 + 1

2(v + w + x + y + z + 1) +1

This is the form of an odd number. Therefore any five odd numbers added together will sum to an odd number.
