Can you add any odd numbers between 1 and 15 and get 30?

@Krrypton,
how many numbers...2, 3...?

The answer is yes; however, more than 2 numbers needed.

@Ragman,
Sorry for not mentioning. 5 odd numbers.

@Krrypton,
No. An even number of such addends will always give you an even sum. As soon as you drop in a single odd number, the result will be odd.

@Krrypton,
1 + 5 + 9 + a 1 immediately followed by 5 for 15 equals 30.

Very good. 5 digits. I had not considered that.
