T2-t1=6, t3-t2=-3,  t3=-6

t3-t2=-3 becomes

-6-t2=-3

-t2=3

t2=-3

t2-t1=6 becomes

-3-t1=6

-t1=9

t1=-9 degrees

Answer:

Step-by-step explanation:

a). Stock price arranged as arithmetic sequence will be,

   5, 8, 11, 14

b). Since, explicit formula of an arithmetic sequence is given by,

   a_n=a+(n-1)d

   Here, T_n = nth term of the sequence

   a = first term

   n = number of term

   d = common difference

   From the table attached,

   First term of the sequence 'a' = 5

   Common difference 'd' = 8 - 5 = 3

   Therefore, explicit formula for the given sequence will be,

   a_n=5+3(n-1)

   a_n=2+3n

c). Slope intercept form of the equation will be,

   y = 3x + 2  

d). Input out values for the graph of the given equation,

   x          0           1          2          3

   y          2           5         8          11

   By using this data we can graph the line.
