What is Sequence and Series?
In Quant, sequence and series are the fundamental concepts of arithmetic. A sequence is also referred to as a progression, which is defined as a successive arrangement of numbers in an order according to some specific rules. A series is formed by adding the elements of a sequence. Let us consider an example to understand the concept of a sequence and series better. 1, 3, 5, 7, 9 is a sequence with five terms, while its corresponding series is 1 + 3 + 5 + 7 + 9, whose value is 25.
A sequence is defined as a successive arrangement of numbers in an order according to some specific rules. Let x1, x2, x3, x4,… be the terms of a sequence, where 1, 2, 3, 4,… represents the term’s position in the given sequence.
- Depending upon the number of terms in a sequence, it is classified into two types, namely a finite sequence and an infinite sequence.
- A series is formed by adding the elements of a sequence.
If x1, x2, x3, x4, ……. is the given sequence, then its corresponding series is given by SN = x1+x2+x3 + .. + xN
Formula for Sequences and Series
Some important formulas related to different series and sequences are:
| Type | Formula | Description |
|---|---|---|
| Arithmetic Sequence | an = a1 + (n − 1)d | nth term of an arithmetic sequence |
| Sum of Arithmetic Series | Sn = 2n(a1 + an) | Sum of the first n terms of an arithmetic series |
| Geometric Sequence | an = a ⋅ rn−1 | nth term of a geometric sequence |
| Sum of Geometric Series (Finite) | Sn = a(1 − rn)/(1 − r) | Sum of the first n terms of a geometric series |
| Sum of Geometric Series (Infinite) | S∞ = a/(1 − r) (For r < 1} | Sum of the infinite geometric series where r < 1. |
| Harmonic Series | Hn = ∑nk=1 (1/k) | Sum of the first n terms of the harmonic series |
Where,
- a1 or a: first term
- an: nth term
- d: common difference in arithmetic sequence
- r: common ratio in geometric sequence
- n: number of terms
- Sn: sum of the first n terms
Difference Between Sequences and Series
| Sequences | Series |
|---|---|
| Set of elements follow a pattern | Sum of elements of the sequence |
| Order of elements is important | Order of elements is not important |
| Finite sequence: 1,2,3,4,5 | Finite series: 1+2+3+4+5 |
| Infinite sequence: 1,2,3,4,5…… | Infinite Series: 1+2+3+4+5+…… |
