WebThe Triangular Number Sequence is generated from a pattern of dots which form a triangle: By adding another row of dots and counting all the dots we can find the next number of the sequence. But it is easier to use this Rule: x n = n (n+1)/2. Example: the 5th Triangular Number is x 5 = 5 (5+1)/2 = 15, WebLet us see the formulas for n th term (a n) of different types of sequences in math. Arithmetic sequence: a n = a + (n - 1) d, where a = the first term and d = common difference. Geometric sequence: a n = ar n-1, where a …
