Answer 2

Answer with explanation:

A Series is:

⇒a summation of quantities whose positions are based upon the natural numbers

This can be explained in the following way

Consider , the arrangement of Quantities

a,   a a,   a a a,   a a a a,  a a a a a,  a a a a a a, a a a a a a a, a a a a a a a a,..........

1  ,    1+1=2  , 1+1+1=3 ,   1+1+1+1= 4     ,       1+1+1+1+1=5  ,      1+1+1+1+1+1=6  ,                1+1+1+1+1+1+1=7    ,    1+1+1+1+1+1+1+1=8

Here, Alphabet "a" are Quantity.

⇒1,2,3,.....are position of Quantity  represented by Natural Number.

In terms of Summation , it can be written as:

 1+2+3+4+5+6+7+8.............

$=\sum_{k=1}^{n} k$
