Find the odd one out in the series: 4, 8, 12, 16, 20, 25.

Step 1: Look at the series of numbers: 4, 8, 12, 16, 20, 25.
Step 2: Identify what the numbers have in common. Check if they are multiples of a certain number.
Step 3: Check if each number can be divided by 4 without leaving a remainder.
Step 4: Divide each number by 4: 4 ÷ 4 = 1, 8 ÷ 4 = 2, 12 ÷ 4 = 3, 16 ÷ 4 = 4, 20 ÷ 4 = 5, 25 ÷ 4 = 6.25.
