12, 24, 26.5, 79.5, ?, 330

A) 211 B) 101.5
C) 82.5 D) 99
 
Answer & Explanation Answer: C) 82.5

The given series 

 

12   24   26.5   79.5   ?   330 follows a pattern that,

 

12 x 2 = 24

 

24 + 2.5 = 26.5

 

26.5 x 3 = 79.5

 

79.5 + 3 = 82.5

 

82.5 x 4 = 330

 

Hence, the missing number is 82.5
