Sequence Formulas - What Are Sequence Formulas? Examples
https://www.cuemath.com/sequence-formulas/
WEBThe sequence formulas include the formulas of finding the n th term and the sum of the first n terms of each of the arithmetic sequence and geometric sequence. Here are the sequence formulas which will in detail be explained below the list of formulas.

WEB3, 5, 7, …. But there are other ways. In this lesson, we'll be learning two new ways to represent arithmetic sequences: recursive formulas and explicit formulas. Formulas give us instructions on how to find any term of a sequence.

WEBa = 1 (the first term) d = 3 (the "common difference" between terms) And we get: {a, a+d, a+2d, a+3d, ... {1, 1+3, 1+2×3, 1+3×3, ... {1, 4, 7, 10, ... Rule. We can write an Arithmetic Sequence as a rule: xn = a + d (n−1) (We use "n−1" because d is not used in the 1st term).

WEBHow explicit formulas work. Here is an explicit formula of the sequence 3, 5, 7, …. a ( n) = 3 + 2 ( n − 1) In the formula, n is any term number and a ( n) is the n th term. This formula allows us to simply plug in the number of the term we are interested in, and we will get the value of that term.

Arithmetic Sequence Formula | ChiliMath
https://www.chilimath.com/lessons/intermediate-algebra/arithmetic-sequence-formula/
WEBArithmetic Sequence Formula. If you wish to find any term (also known as the [latex]{{nth}}[/latex] term) in the arithmetic sequence, the arithmetic sequence formulashould help you to do so. The critical step is to be able to identify or extract known values from the problem that will eventually be substituted into the formula itself.
