We call \(a_1\) the first term of the sequence, \(a_2\) the second term of the sequence, \(a_3\) the third term of the sequence, and so on. The term \(a_n\) is called the nth term of the sequence, or the general term of the sequence.

Here we will learn about different types of sequences including arithmetic sequences, geometric sequences and quadratic sequences and how to generate them and find missing terms, along with special sequences like the fibonacci sequence.
The first term is in position 1, the second term is in position 2 and so on. Position to terms rules use algebra to work out what number is in a sequence if the position in the sequence is...
Oct 18, 2018 · The odd terms in the sequence are negative, and the even terms are positive. Therefore, the \(n^{\text{th}}\) term includes a factor of \((−1)^n\). Next, consider the sequence of numerators \({1,2,3,…}\) and the sequence of denominators \({2,3,4,…}\).
difference. in the terms. This sequence is going up by four each time, so add 4 on to the last term to find the next term in the sequence. 3, 7, 11, 15, 19, 23, ... To work out the term...
To refer to any term of a sequence, we use the \(u_n\) notation, where \(n\) indicates the term we're referring to. For instance, if we're dealing with the sequence \(3,7,11,15,19,23, \dots \) we would refer to the first, second and third terms as: \[u_1 = 3\] \[u_2 = 7\] \[u_3 = 11\] We'll often refer to the \(n^{\text{th}}\) term of a ...
Dec 29, 2020 · The terms of this sequence obviously grow without bound. However, it is also true that these terms are all positive, meaning \(0<a_n\). Thus we can say the sequence is unbounded, but also bounded below.
