How to add 1 3 5 7 9 11 13 15 17 to grt 30 answer

Answer 1

The sum of three odd numbers gives an odd number
So, the sum of  given odd numbers doesn’t results 30
So, it is an impossible factor
here we can't use 3! too
because 3! [3×2×1] results a even number 6
so we can’t use it.
If there will be an allowance of factorials, then the answers will be
3! + 15 + 9 =30
3! + 11 + 13 = 30
3!+1+5+7+11=30
3!+1+3+7+13=30

Answer 2

It can be possible as:-15+13(3-1)
