Choose the number that continues the series in the most sensible way.3 27 6 19 12 [?]A24B38C18D11E4

The pattern in the series is alternating between multiplying by 9 and subtracting 8.

Starting with 3:

• 3 multiplied by 9 equals 27
• 27 minus 8 equals 19
• 19 multiplied by 9 equals 171
• 171 minus 8 equals 163
• 163 multiplied by 9 equals 1467
• 1467 minus 8 equals 1459

However, the series provided does not follow this pattern. It seems there might be a mistake in the series. The series provided is 3, 27, 6, 19, 12, and then a missing number.

If we consider the series as two separate sequences: 3, 6, 12 and 27, 19, the pattern could be:

• For the first sequence (3, 6, 12), each number is multiplied by 2. So, the next number would be 12*2 = 24.
• For the second sequence (27, 19), each number is subtracted by 8. So, the next number would be 19-8 = 11.

So, the missing number could be either 24 or 11, depending on which pattern the series is supposed to follow.

Therefore, the answer could be either A24 or D11.
