What are number series?

A number series is a number-based sequence. We will need to identify the rules that lead to the formation of a number series for the number series questions. A series is, roughly speaking, a description of the process of adding infinitely many quantities, one after the other, to a given starting quantity. Calculus and its generalization, mathematical analysis, include a significant portion of the study of series. Even when studying structures that are finite, series are utilized in most areas of mathematics.

Given A square table can seat 4 people

and 2 tables can seat 6 people,

tables needed for  26 people let be n

according to condition arrangement is explained in figure

let n tables are kept together and 26 people sit together in long table

1 + n + n + 1 = 26

2n + 2 = 26

2n = 26 - 2

2n = 24

n = 12

Hence 12 tables required for 26 members.
