IQ pattern test
Can you solve this IQ pattern?
This quick sequence checks whether you can spot a rule from changing gaps instead of guessing from the last number.

Quick answer
Answer: 42
The gaps are 4, 6, 8, and 10. The next gap should be 12, so 30 + 12 = 42.

Compare each number with the one before it.
2
Write down the gaps: 4, 6, 8, 10.
3
Notice that the gaps increase by 2 each time.
4
