Answer:
4n-10, Answer is D
Explanation:
First we will use n as any number.
the difference between each of the numbers is +4
This creates first part of the formula.
4n...
If you do 4n and replace n as one (For the first number of the sequence) then 4×1=4. You then have to find out how much you need to add or subtract to get -6 so the difference between 4 and -6 is -10.
This creates the second part of our formula.
4n - 10
You can check this by doing the same thing for the second number and replacing n with 2.
2×4=8
8 - 10= -2 which is the second number in the sequence which confirms this is correct.
