Answer:
-8
Step-by-step explanation:
Its actually simple once you get the basics
Find out the difference between the first two digits given e.g 8,6: the difference is 2 so you check if it's the same difference e.g 6,4: the difference is also 2 so you keep subtracting or adding 2 as the case may be.
Answer:
n=-6
Step-by-step explanation:
First, you want to isolate the variable. So, subtract 4 from both sides. You will then have -2-4 equals n. Also known as -6 equals n.
The equation would be Y=-3X+5
This is because there is a y-intercept(meaning Y value at X=0) of 5 and a slope(meaning the amount the y value changes by every time the x value increases by one) of -3.
Answer:
a) 6
Step-by-step explanation:
Expanding the polynomial using the formula:
Also
I think you mean 
We can deduce that this term will be located somewhere in the middle. So I will calculate 
.
For 
Note that we actually don't need to do all this process. There's no necessity to calculate the binomial, just 
For
