The {eq}n^{th} {/eq} term of the sequence means the general formula of the sequence that is used to find any term of the sequence. To find a given term of the sequence, we substitute the value of {eq}n {/eq} in the {eq}n^{th} {/eq} term of the sequen...

Find the first 10 terms of the sequence. {eq}a_1 = -y {/eq}, {eq}d = 5y {/eq} Arithmetic Sequence In mathematics, an arithmetic sequence refers to the pattern of numbers that is generated when we add a constant value to the current term to form the next term in the seq...
Find out the first five terms (beginning with n = 1) of the sequence given. {eq}\left\{an\sin\left( \dfrac{n\pi}{2}\right)\right\} {/eq} General Term of a Sequence: If we want to determine any of the terms of a sequence, we must know the expression for its ...
1. Write down the general term of each of the following sequences in simplest form: So far I have been using guess and check to find the solutions, but it doesn't seem much use when you get to a sequence more complicated like this: 1, -4, 7, -10, 13, ... I really need to...
