Let’s compare this list with the first 10 square numbers: The first 10 square numbers. (An interesting observation is that 36 is both a triangular number and a square number, and appears in both lists.) We can see that the square number 9 equals the sum of triangular numbers 3 and 6.
WebThe n th term of this sequence is 6n – 2. To find the 21 st term, n = 21 (6 x 21) – 2 = 124 The 21 st term is 124. E.g. Given the n th term rule, 3n + 4, find the 20 th and 100 th term for this sequence. To find the 20 th term, n = 20 (3 x 20) + 4 = 64 To find the 100 th term, n = 100 (3 x 100) + 4 = 304.
