Answer 2

To determine the number that should be placed in the parentheses, let's try to identify the pattern in the given sequence: 6, 10, 5, 9, 4.

If we look at the differences between consecutive numbers, we get:

10 - 6 = 4 5 - 10 = -5 9 - 5 = 4 4 - 9 = -5

We can see that the differences alternate between 4 and -5. So, the next difference should be 4. Now, let's find the next number in the sequence:

4 + 4 = 8

So, the number that should be placed in the parentheses is 8.

The completed sequence is: 6, 10, 5, 9, 4, (8).
