WebThis is an expression for the nth triangular number so we have to prove that this is the case. We do this by constructing the nth triangular number in counters. The number of counters in the bottom row of the nth triangular number is n. The number of counters in the row above that is n – 1. The number of counters in the row above that is n – 2. WebSquare numbers appear along the diagonal of a standard multiplication table. Connections with triangular numbers If you count the green triangles in each of these designs, the sequence of numbers you see is: 1, 3, 6, 10, 15, 21, …, a sequence called (appropriately enough) the triangular numbers.
