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

​

Logic: Bottom Number = (Top right Number)²- (Top left Number)²​

In 1st Figure:

60 = (8)²- (2)²​

60 = 64 - 4

60 = 60

In 2nd Figure:

5 = (3)²- (2)²​

5 = 9 - 4

5 = 5

In Figure 3rd:

? = (8)²- (6)²​

? = 64 - 36

? = 28

Missing number = 28

Thus , the correct answer is (d)
