Answer:
26 tiles
Explanation:
In the picture attached, the pattern is shown.
From the picture, we can see that:
- the 1st pattern has 6 tiles
- the 2nd pattern has 6 + 5 = 11 tiles
- the 3rd pattern has 11 + 5 = 16 tiles
Therefore, the next patterns will have:
- 4th pattern, 16 + 5 = 21 tiles
- 5th pattern, 21 + 5 = 26 tiles
