What is the sum of the first two numbers in the series: 4, 12, 6, 9?

To determine the sum of the first two numbers in the series, you need to add the first number, which is 4, and the second number, which is 12.

When you perform the addition:

4 + 12 = 16.

Thus, the sum of the first two numbers in the series is 16. This makes the answer correct because it directly reflects the addition of those two specific values in the sequence.
