To find the rule for the sequence 8, -1, -10, -19..., we need to look for a pattern in the differences between consecutive terms. Let's calculate the differences:
-1 - 8 = -9
-10 - (-1) = -9
-19 - (-10) = -9
...
As we can see, the differences between consecutive terms are always -9. So, we can conclude that the rule for this sequence is to start with 8 and subtract -9 repeatedly.
To find the next three terms, we apply the rule:
-19 - (-9) = -10
-10 - (-9) = -1
-1 - (-9) = 8
Therefore, the next three terms of the sequence are -10, -1, and 8.
For the sequence -4, -8, -16, -32..., we can also calculate the differences to find the pattern:
-8 - (-4) = -4
-16 - (-8) = -8
-32 - (-16) = -16
...
The differences between consecutive terms are multiples of 4. Specifically, each term is multiplied by 2. So, the rule for this sequence is to start with -4 and multiply each term by 2 repeatedly.
Next three terms:
-32 * 2 = -64
-64 * 2 = -128
-128 * 2 = -256
Therefore, the next three terms of the sequence are -64, -128, and -256.
For the sequence 48, 40, 32, 24..., we can calculate the differences:
40 - 48 = -8
32 - 40 = -8
24 - 32 = -8
...
The differences between consecutive terms are always -8. Therefore, the rule for this sequence is to start with 48 and subtract 8 repeatedly.
To find the 7th term, we apply the rule:
48 - 8 = 40
40 - 8 = 32
32 - 8 = 24
24 - 8 = 16
16 - 8 = 8
8 - 8 = 0
0 - 8 = -8**
Therefore, the 7th term in the sequence is -8.
