Solution

The correct option is C 2x+1

The column of 'number of matchsticks - 1' forms the multiplication table of 2. i.e., 2, 4, 6, 8, ...

Let the number of triangles be x.

The number of matchsticks used in each pattern is 1 more than 2 times the number of triangles in it.

The number of matchsticks used in each pattern = 2x+1.
