Consider as an alternate series.
4.5 * 1/2 = 2.25
18 * 3/2 = 27
2.25 * 4/3 = 1.6875
27 * 5/4 = 33.75.
Therefore, the series is 4.5, 18, 2.25, 27, 1.6875, 33.75.

The given series are:
4.5, 18, 2.25, X, 1.6875, 33.75
We have to find, the value of missing number (x) = ?
Solution:
The pattern follow:
Previous number × 4, Previous number ÷ 8, Previous number × 12, Previous number ÷ 16, Previous number × 20, .......
18 = 4.5 × 4 = 18
2.25 = 18 ÷ 8 = 2.25
x = 2.25 × 12 = 27
1.6875 = 27 ÷ 16 = 1.6875
33.75 = 1.6875 × 20 = 33.75
∴ Missing number (x) = 27
Thus, the value of "missing number (x) is equal to 27".
