In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8. Number Sequences. WebThe nth triangle number is the number of dots composing a triangle with n dots on a side, and is equal to the sum of the n natural numbers from 1 to n. The general representation of a triangular number is Tn= 1 + 2 + 3 + 4 +...+ (n-2) + (n-1) + n, where n is a natural number. This sum is Tn = n * (n + 1) / 2.
