Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.

6 : 96 :: 8 : 144 :: 5 : ?

75

The pattern followed in the given series is:

(First term + 10) × First term = Second term

Let's apply the pattern on the given series:

6 : 96 :: 8 : 144 :: 5 : ?

(First term + 10) × First term = Second term

(6 + 10) × 6 = 96

96 = 96

6 : 96 :: 8 : 144 :: 5 : ?

(8 + 10) × 8 = 144

144 = 144

6 : 96 :: 8 : 144 :: 5 : ?

(5 + 10) × 5 = Answer

75 = Answer
