10 points if anyone can help me finish this.

1)Use your pattern skills to copy and complete the table below.
IN(x) 2 , 10 , 6 , 7, -3 , ? , -10 ,100, x
out(Y) 5,21,13, ? , ? , -15 , ? , ? , ?
A.Explain in words what is being done to the input value ,x, to produce the output value,y.
B.Write the process you describe in part (a)in algebraic symbols.
2)Evaluate each expression below.
a)For y=5+8x when x= 4 ,what does (y) equal ?
b)For a=3-5c when c=0.5,what does (a) equal ?
c)For n=2d^-5 when d= -2,what does (d) equal ?
d)For v= -3(r-3)when r =-1,what does (v) equal ?

1) In question one the equation you need to finish the pattern is :2x +1 = y.
2,10,6,7,-3,-8,-10,100,x
5,21,13,15,-5,-15,-19,101,y
X is being being multiplied by 2 and then we are adding 1 to obtain y.
2x+1=y
a)y=17
b)a=.5
c)n=-1/16
d)v=12
