Select the missing number from the given series.81, 41.5, 42.5, 64.75, 130.5, ?, 982.751. 327.502. 327.253. 326.254. 327.65

Answer» Correct Answer - Option 2 : 327.25

The logic is as:

81× 0.5 + 1 = 41.5

41.5× 1 + 1 = 42.5

42.5× 1.5 + 1 = 64.75

64.75× 2 + 1 = 130.50

130.50× 2.5 + 1 = 327.25

327.25× 3 + 1 = 982.75

Hence, the missing term is327.25.
