Given the explicit formula for an arithmetic sequence find the first five terms and the term named in the problem.
This unit introduces sequences and series, and gives some simple examples of each. It also explores particular types of sequence known as arithmetic progressions (APs) and geometric progressions (GPs), and the corresponding series.
17 kwi 2018 · The value of the nth term of an arithmetic sequence is given by the formula. an = a1 + (n - 1)d where a1 is the first term in the sequence, n is the position of the term in the sequence, and d is the common difference. Identify a1, n, and d for the sequence. ( n 1) d to find it.

An explicit formula for this arithmetic sequence is given by an = a + (n −1)b, n ∈ N, a recursive formula is given by a1 = a and an = an−1 + b for n > 1. Here are some examples of arithmetic sequences, see if you can determine a and b in each case: 1, 2, 3, 4, 5, ... 2, 4, 6, 8, 10, ... 1, 4, 7, 10, 13, ...
There are two major types of sequence, arithmetic and geometric. This section will consider arithmetic sequences (also known as arithmetic progressions, or simply A.P). The characteristic of such a sequence is that there is a common difference between successive terms. For example: 1, 3, 5, 7, 9, 11, . . .
Sequences. Sequences are just ordered lists of numbers such as this one. f1; 2; 3; 4; 5; g. We label each term with an index so we can keep track of it. We’ll call the first term a1, the second term a2, and so on. So we would notate the general n th term as an.
