The image shows a task that asks you to find the missing number in a sequence.

Let’s look at the numbers given:

> 2, 4, 8, 16, ?

We need to figure out what comes next.

Step 1: Look at how each number changes from one to the next.

- From 2 to 4 → we multiply by 2 (2 × 2 = 4)
- From 4 to 8 → we multiply by 2 (4 × 2 = 8)
- From 8 to 16 → we multiply by 2 (8 × 2 = 16)

So the pattern is: multiply by 2 each time

Step 2: Apply the same rule to get the next number.

→ 16 × 2 = 32

Step 3: Check if this makes sense.

Sequence:
2 → 4 → 8 → 16 → 32
Each step doubles the previous number. Yes, it fits perfectly.

Final Answer:
32
