2x^4(or 2x to the fourth power
Answer:
Okay let me explain this to you so you understand
So what does f(n) mean?
Well F(n) is saying the function, of n.
Basically we need to make n be any random number.
Well what number do we choose?
In your question, it says n is greater than or equal than 2.
lets start with 2
f(n-1)+2
f(2-1)+2
1+2
3
f(2) is 3
lets do this 4 more times
that leaves us with the first 5 terms
these 5 terms are
3

Answer:
x=8
Step-by-step explanation:
-4 = 12 - 2x
when plus 12 goes to the left hand side it changes its sign so,
-4 -12 = -2x
- * - is plus so add 4 and 12 but keep the sign - because 12 is the greatest number and its sign is -
-16=-2x
when -2 comes to the left hand side it changes its from multiplication to division.So,
-16/-2=x
8=x
we will get positive 8 because minus and minus also gets cancel.
