the sum of all the terms in a sequence, however, there has to be a definite relationship between all the terms of the sequence

any arrangement of any objects or a set of numbers in a particular order followed by some rule, If a1, a2, a3, a4..... etc. denote he terms of a sequence, then 1,2,3,4.... denotes the position of the term

2 types of a sequence

A sequence in which every term is created by adding or subtracting a definite number to the preceding number is an arithmetic sequence.

A sequence in which every term is obtained by multiplying or dividing a definite number with the preceding number is known as a geometric sequence.

if the reciprocals of all the elements of the sequence form an arithmetic sequence.

form an interesting sequence of numbers in which each element is obtained by adding two preceding elements and the sequence starts with 0 and 1. Sequence is defined as, F₀ = 0 and F₁ = 1 and F_n = F_n-1 + F_n-2

how to get the nth term of an arithmetic sequence?

If we add or subtract by the same number each time to make the sequence

is an ordered set of numbers that have a common difference between each consecutive term
