Suppose we use matchsticks to form letter

Here, we used 2 matchsticks

 

Suppose, we want to make more than one L

So

2 Ls require 4 matchsticks

3 Ls require 6 matchsticks

4 Ls require 8 matchsticks

And so on

 

So,

Can we say that

Number of matchsticks = 2 × Number of L’s

  Writing n = number of L’s

Number of matchsticks = 2n

Let’s Check ?

For n = 1,  Number of matchsticks = 2 × 1 = 2

For n = 2,  Number of matchsticks = 2 × 2 = 4

For n = 2,  Number of matchsticks = 2 × 3 = 6

 

So writing

Number of matchsticks = 2n

Makes our job easier

 

Suppose we have to make 100 L’s

Number of matchsticks = 2 × 100

       = 200
