Oh, dude, it's like super simple. The 50th triangular number is just the sum of all the numbers from 1 to 50. So, you can use the formula n(n+1)/2, where n is 50 in this case. Plug it in, do the math, and boom, you've got your answer. It's like math, but with a little extra pizzazz.

The formula for the nth triangular number is Tn = n(n+1)/2. To find the 50th triangular number, substitute n = 50 into the formula: T50 = 50(50+1)/2 = 50(51)/2 = 1275. Therefore, the 50th triangular number is 1275.
Oh honey, it's simple math. The formula for the nth triangular number is n(n+1)/2, so for the 50th triangular number, you just plug in 50 for n and calculate. It's not rocket science, darling. Just a little bit of arithmetic.

The 50th triangular number is (50)(51)/2=1275
A number is a single term so there cannot be a 50th term for a number.
