all even perfect numbers are triangular numbers, and every alternate triangular number is a hexagonal number given by the formula: \(\begin{array}{l}m_{p}2^{p-1}=\frac{m_{p}(m_{p}+1)}{2}=t_{mp}\end{array} \) where m p is a mersenne prime. for example, the third ...

a1 = the first term in the series, r = the common ratio of the series, which is the amount between each number. The formula is only valid if |r| < 1, which can be written equivalently as -1 < r < 1. In other words, if r is between -1 and 1, then the series has a sum...
FormulaThe name implies that terms are recurring,and these formulas can be used to determinethe next term in a series or sequence fromthe preceding one.Ex: t1 = 3Usually we are given the first term.t 2 = t1 + 5 From this we can derive a formula tot3 = t 2 + 5 find the way ...

A Sequence is a list of things (usually numbers) that are in order.Infinite or FiniteWhen the sequence goes on forever it is called an infinite sequence, otherwise it is a finite sequenceExamples: {1, 2, 3, 4, ...} is a very simple sequence (and it is an infinite sequence) {20,...
62. [T] Consider a series combining geometric growth and arithmetic decrease. Let a1=1a1=1. Fix a>1a>1 and 0<b<a0<b<a. Set an+1=a.an−ban+1=a.an−b. Find a formula for an+1an+1 in terms of anan, aa, and bb and a relationship between aa and bb such that anan conv...
