Suppose we use matchsticks to form letter
Here, we used 2 matchsticks
Suppose, we want to make more than one L
So
2 L's require 4 matchsticks
3 L's require 6 matchsticks
4 L's 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 = 3, 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
