Re: Series of patterns

Hi..

This is the answer for your question...

Pattern number = N

The first figure = 2 grey and 2 white

The second figure = 3 grey and 4 white

The third figure = 4 grey and 6 white

Continuing this way, we will get

The N-th figure will be,

(N+1) number of white + 2N number of grey.

Therefore,

Expression for the number of grey tiles= 2N

Expression for the number of white tiles = N+1

The total number of tiles in the N th figure = N+1+ 2N = 3N + 1.

Hope you have understood the problem.
