First … WebNov 5, 2024 · The formula for the nth term of the sequence is the one you have already mentioned. Also rightly so you have identified that it will lead to an inefficient algorithm and stack overflow. You can look into dynamic programming approach where u calculate F(I,N) just once and just reuse the value. For example this is how the fibonacci seq is calculated.

WebFeb 5, 2010 · Number Sequences. In the sequence 2, 4, 6, 8, 10... there is an obvious pattern. Such sequences can be expressed in terms of the nth term of the sequence. 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. WebSo now twice the 4th triangular number plus 5 = 5 2. Rearranging gives. 4th triangular number = (5 2 – 5)/2. Using this same argument on the nth triangular number gives. nth triangular number = [(n + 1) 2 – (n + 1)]/2. Level 5 students should probably see how this works for the specific examples (n = 5, 6, 7).

This general description of the term leads to the closed form, or an expression representing each figurate number. Example: T = n(n+1)/2 where T represents any triangular number. If one wants the 4th triangular number, n = 4 and T4 = 4(5)/2 or T4 = 10. If one wants the 50
WebNov 24, 2024 · A triangular number is a number that can be represented by a pattern of dots arranged in an equilateral triangle with the same number of dots on each side. The first triangular number is 1, the second is 3, the third is 6, the fourth 10, the fifth 15, and so on. You can see that each triangle comes from the one before by adding a row of dots on ...
