In case 1, there are 4 stars shown.

In case 2, there are 6 stars shown.

In case 3, there are 9 stars shown.

How many stars will there be in case 11?

I'm just gonna assume that this is a geometric series, since cases 1,2, and 3 can match a geometric series.

 

The first term is 4, and the common ratio is 3/2. Case 11 will be equal to 4*\((\frac{3}{2})^{10}\)=\(\frac{3^{10}}{256}\).

 

If this is not a geometric series then I don't really know how to help.
