Answer:

Step-by-step explanation:
Look at the component form of each vector.
Note that vector c is <4,4> and vector d is <-2,-2>
If one imagined the line that contained each vector, the line for both would have a slope of 1, because 
Since they have the same slope they are parallel, but since they are in opposite directions, we often call them "anti-parallel" (simply meaning parallel, but in opposite directions).
If two vectors are parallel, one vector can be multiplied by a scalar to result in the other vector. This means that there is some number "k", such that
, or equivalently,
and
.
If
and
, we just need to substitute known values and solve for k:

Double checking that k works for the y-coordinates as well:

? 

So, 
Answer:
362881
Step-by-step explanation:
The right sequence should be
2,3,7,25,121,721,5041,40321, 362881
Here, the formula used is a(n)=n!+1 where n=1 to infininity
n(1) =2=1!+1=2
n(2)= 3=2!+1=3
n(3)=7=3!+1=7
n(4)=25=4!+1=25
n(5)=121=5!+1=121
n(6)=721=6!+1=721
n(7)=5041=7!+1=5041
n(8)=40321=8!+1=40321
n(9)=362881=9!+1=362881
