Answer:
The 96th term of the arithmetic sequence is -1234.
Step-by-step explanation:
first term (a)=1
second term (t2)=-12
common difference (d)= t2-a
d=-12-1
d=-13
96th term (t96)=?
We know that,
t96=a+(n-1)d
t96=1+(96-1)(-13)
t96=1+95(-13)
t96=1-1235
t96=-1234
Answer:
B. -1
Step-by-step explanation:
If we have a parabola whose equation is:

The line of symmetry is calculated as:

Now, we have the equation
and the line of symmetry is 
Where:

So, we can replace
by -4 and
by -2 and solve for
using the following equation as:

It means that the equation of the parabola is equal to:
