Well, its simple really. The expression for triangular is n(n+1) over 2 (divided by 2). You would then plug in the number 4 (because of 4th triangular). The equation would now be 4(4+1) over 2. Now you would do the parentheses making the problem 4(5) (4 times five) over 2. Than you would multiply 4 and 5 now making your problem 20 over 2 (or 20 divided by 2). 20 divided by 2 equals 10 making the final answer 10.
