@lanana I can't really tell what symbol is in between those numbers. Are those subtraction signs or multiplication signs?

Just notice the pattern.

that still doesn't help me .... @ranga

ranga · Answer

If you look at the right you see a pattern: 
First one is:  1 x 2
Second one is:  2 x 3
Third one is:  x 4
Fourth one is: 4 x 5
Fifth one is: 5 x 6

So the tenth one will be: 10 x (10+1) = 10 times 11

The answer is the last choice.
