This paper is presented to find the term to-N from sequence in polynomials addition through a linear equation system.The problem to be put forward in this paper is that people have a hunch that the general formula of the term to-N in sequence is unique. But actually the case is infinite...

The formula n22 − n2 + 1 can be simplified to n(n-1)/2 + 1So by "trial-and-error" we discovered a rule that works:Rule: xn = n(n-1)/2 + 1Sequence: 1, 2, 4, 7, 11, 16, 22, 29, 37, ...Other Types of Sequences...
Your turn Write a recursive formula for the sequences below Your turn Write a recursive formula for the sequences below. Step 1 : Determine if it is arithmetic or geometric. Step 2 : Plug in to either the geometric or arithmetic recursive formula. Step 3 : Make sure you tell us what a1...
So, the next number for the fifth position is 52=25. A square number can be computed by the formula Sn=n2. Pentagonal Number Sequence The pentagonal numbers follow these sequence: a) The first pentagonal number is 1. b) The second pentagonal number is 1 + 4 = 5 ...

The sequence goes 1, 3, 6,10, 15, 21, 28, ... At this point, they won't have a formula for the nth triangular number, just a procedure for finding it. 1. 第n个三角数字是数字的总和从1到n。 序列去1, 3, 6,10, 15, 21, 28,… 这时,他们不会有一个惯例为第n个三角数字,方法...
Creating a Formula of a Geometric Sequence What I'd rather have is a formula that will tell me how many new hits I get at any time simply by substituting in a number. Looking back at the entries we came up with so far will help us to see the pattern that we can try to generalize...

Finding factor sequence of 1,5,x,13, x would be 9. 5 in the 4th suggests factorization is inculded. But I am not sure I can find it without your answer. Ah, ok I see now. Thank you for the help. While it still seems to be a bit of a challenge, that at least helps signif...
