What is the nth term of a sequence? Answer and Explanation: There are two main types of sequences/progressions. Arithmetic Sequence - The difference between any two consecutive terms is the same for all... Learn more about this topic: ...
A sequence {eq}\{ {x_n}\} {/eq} is a function {eq}f:\textbf{N} \to \textbf{R} {/eq} which can be represented as : {eq}\left\{ {{x_1},{x_2},{x_3},...,{x_n}...} \right\} {/eq}, where {eq}{x_n} {/eq} be the...
So if the square numbers have nth term of n^2, then the nth term of this sequence is 2n^2. Question:Find the first three terms of this 3n+2? Answer:You can find the terms by substituting 1,2 and 3 into this formula. This gives 5,8,11. ...

nth term (a n ) sum of the first n terms (s n ) all three terms represent the property of arithmetic progression. we will learn more about these three properties in the next section. first term of ap the ap can also be written in terms of common differences, as follows; a, a + ...
Theorem: The sum of nth terms of an AP with first term a and common difference d is Sn=n/2(2a+(n-1)d)
The formula an = a + ( n – 1 ) d is used to get the general term (or) nth term of an arithmetic progression (AP) whose first term is a, and the common difference is d. For example, we have the sequence 5, 8, 11, 14, 17, 20, 23, and 26....
