What two triangular numbers 43?
The two triangular numbers that sum to 43 are 28 and 15. Triangular numbers are formed by the formula ( T_n = \frac{n(n + 1)}{2} ). For this case, 28 corresponds to ( T_7 ) (when ( n = 7 )) and 15 corresponds to ( T_5 ) (when ( n = 5 )). Thus, ( T_7 + T_5 = 28 + 15 = 43 ).
