Finding the Odd Number Out 

We need to find the odd number out from the given series:

396, 462, 572, 427, 671, 264.

Upon inspecting the numbers, let’s look at the sums of the digits of each number:

• 396 : 3 + 9 + 6 = 18
• 462 : 4 + 6 + 2 = 12
• 572 : 5 + 7 + 2 = 14
• 427 : 4 + 2 + 7 = 13
• 671 : 6 + 7 + 1 = 14
• 264 : 2 + 6 + 4 = 12

From the sums, we notice that all numbers except 427 have sums that are divisible by 2 (i.e., even sums), while 427 has an odd sum of 13.

Thus, the number that does not follow the pattern is 427.

Thus, the correct answer is: 427.
