Studt the list of numbers and use it’s pattern to predict the next three numbers describe the pattern
2 answers:
If you find the difference between the numbers you'll see that if you add 2, 4, 8, 16,... you'll get that sequence!
E. g.
1 + 2 = 3
3 + 4 = 7
7 + 8 = 15
So I'll predict that to gt the next nunber, you'll need to add this to current number:
Where n is just the position of the current number (1st, 2nd, 3rd). So the number after 31 should be:
And the number after 63 should be:
Now you try the last one! You can comment the answer and I'll check if it's right.

Answer:
The vertex (h,k) is (-4,-7).
Step-by-step explanation:
I assume you are looking for the vertex .
The vertex form of a quadratic is where the vertex is (h,k) and a tells us if the parabola is open down (if a<0) or up (if a>0). a also tells us if it is stretched or compressed.
Anyways if you compare to
, you should see that
.
So the vertex (h,k) is (-4,-7).
