WebThe formula for expressing how to find a triangular number is known as n (n + 1) / 2. For example, if we’re looking to find the fifth triangular number, we replace n with the number 5. This turns the formula into 5 (5 + 1) / 2. In other words, we want to find (5 × 6) ÷ 2. All we need to do to find our answer is to half 30. WebT (n) = n + (n – 1) + (n – 2) + … + 2 + 1. This is an expression for the nth triangular number so we have to prove that this is the case. We use an algebraic approach for this …
