Most people immediately assume there must be a quick trick, but the key is to slow down and look at how the numbers are changing step by step.
Let’s break it down carefully.
We start with the number 2.
To get to the next number (4), we multiply by 2:
2 × 2 = 4
Now we move from 4 to 8.
Again, the same pattern applies:
4 × 2 = 8
So far, the pattern is consistent — each number is being multiplied by 2 to get the next one.
Now we apply the same logic to find the missing number:
8 × 2 = 16
So the sequence continues by doubling each time.
This type of pattern is known as a geometric progression, where each number is multiplied by a constant value (in this case, 2).
At first, it feels almost too easy — and that’s exactly why many people overthink it and look for a more complicated answer. But sometimes, the simplest pattern is the correct one.
Final Answer: 16
If you got it right, you’re thinking clearly.
If not, don’t worry — puzzles like this are all about training your brain to notice patterns step by step.
