The nth triangular number is n(n+1)/2
A tetrahedron (triangular pyramid).
When you add two consecutive triangular numbers, the result is a perfect square. For example, the first two triangular numbers are 1 (T1) and 3 (T2), and their sum is 4, which is (2^2). In general, the sum of the (n)-th triangular number (T_n) and the ((n+1))-th triangular number (T_{n+1}) equals ((n+1)^2). This relationship holds for all pairs of consecutive triangular numbers.
A triangular number is a figurate number that represents a triangle with dots. The n-th triangular number, denoted as T(n), can be calculated using the formula T(n) = n(n + 1)/2, where n is a positive integer. For example, the first few triangular numbers are 1, 3, 6, 10, and 15, corresponding to n values of 1 through 5. If W refers to a specific triangular number, it would depend on the value of n chosen.
