To find the missing number in the given series, let's analyze the pattern:
The series starts with 84 and decreases with each subsequent number.
The first number is divided by 2 to get the second number.
The second number is divided by 2 to get the third number.
The third number is divided by 2 to get the fourth number.
Using this pattern, we can find the missing number in the series.
Step 1: 84 ÷ 2 = 42
Step 2: 42 ÷ 2 = 21
Therefore, the missing number in the series is 21.
Let's verify this with the options given:
a) 10.5: This option doesn't fit the pattern and is not the missing number.
b) 16.8: This option also doesn't fit the pattern and is not the missing number.
c) 18.4: This option doesn't fit the pattern and is not the missing number.
d) 19.6: This option doesn't fit the pattern and is not the missing number.
So, the correct answer is option 'B' (16.8).
In conclusion, the missing number in the series 84, 42, 28, 21 is 16.8.
