(l+3+5+...+m)+(l+3+5+...+n)=(l+3+5+...+29)

what is m+n? (both m and n are odd positive integers)

 

in the question it's written as L's, not 1's.

(1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23)  +  (1, 3, 5, 7, 9, 11, 13, 15, 17)==(1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29) ==225. Therefore:

 

m ==23, and:

n ==17

 

m  +  n ==23  +  17 == 40
