6 + (10 - 4)2 - 20 = 6 + 12 - 20 = 18 - 20 = -2
Assuming that the two in the middle of the expression is multiplied by (10 - x) the answer would be -2. I apologize if I did not read your question right.
Given:
The sequence is
1, 4, 16, 64
To find:
The general term of the given sequence.
Solution:
We have, the sequence
1, 4, 16, 64
Here, the ratio between two consecutive terms is same. So, it is a geometric sequence.
First term is:

Common ratio is:



The nth term of a geometric sequence is
...(i)
Where, a is the first term and r is the common ratio.
Putting a=1 and r=4 in (i), we get


Therefore, the general term of the given sequence is
.
Answer:

Step-by-step explanation:
slope:

Equation, with the point (19, -9):





Hope this helps
The answer is 117 miles and if you were given the miles intead multiply 117 (or whatever the number would havw been) by 8 then divid th product by 312 to get the amount of gas used
2^3 * 2^-5 = 2^(3 + (-5) = 2^(3 - 5) = 2^-2
