Which two triangular numbers total 43?

Answer 1

28 and 15

Answer 2

Let's denote the two triangular numbers as ( n(n+1)/2 ) and ( m(m+1)/2 ). We can set up the equation ( n(n+1)/2 + m(m+1)/2 = 43 ) and simplify it to ( n^2 + n + m^2 + m = 86 ). Since the two triangular numbers must be integers, we can try different values for n and m to find the solution. The two triangular numbers that total 43 are 6 and 37.

Answer 3

Oh, dude, you're hitting me with some math vibes! So, like, the triangular numbers are like those numbers you get when you add up all the numbers from 1 to a certain number. If we're talking about 43, you'd be looking at the 9th and 10th triangular numbers, which are 36 and 45. So, yeah, 36 + 45 = 81, not 43. Math, man, it's a trip.
