Question

| Cats | 3 | 6 | ? | 15 |
| Dogs | 4 | 8 | 12 | 20 |

What is the missing value for Cats?

Answer 1

To find the missing value for Cats in the given sequence, let's analyze the numbers provided:

For Dogs, the values are: 4, 8, 12, 20. Let's look for a pattern:

- 4 to 8 is an increase of 4.
- 8 to 12 is an increase of 4.
- 12 to 20 is an increase of 8.

It seems there is a pattern where the differences can be described by a sequence themselves: 4, 4, and then 8 (which is like doubling the previous increment).

Now, let's examine the values for Cats: 3, 6, ?, 15.

- 3 to 6 is an increase of 3.
- From 6 to ? we need to find the increase.
- Then we see that we reach 15 afterwards.

Now let's analyze if we can figure out a similar pattern:

If we follow the same increase of the previous step by 3:
- From 3 to 6, the increase is 3.
- If we assume the next increase in a similar pattern might also be 3, then:
- 6 + 3 = 9.

Now we need to check if this fits for the next increase to reach 15:
- From 9 to 15:
- This is an increase of 6 (which is double the previous 3).

So, the complete pattern for Cats could look like:
- 3 (increase of 3) to 6 (increase of 3) to 9 (increase of 6) to 15.

Thus, the missing value for Cats is **9**.
