Study the given pattern carefully and select the number that can replace the question mark (?) in the third figure.

​

Logic: Difference of upper numbers and below numbers are same.

Let's check all the figures; 

Figure (I); 18 - 8 = 10, 17 - 7 = 10

Figure (II); 22 - 15= 7, 14 - 7 = 7 

Similarly;

Figure (III);18 - 14 = 4,

? - 13 = 4

? = 13 + 4 

Thus, the correct answer is (c) 17.
