The angle of x is matching the angle of 113
(2-8)/(4+6)
-6/10
-3/5
slope is -3/5
The rule is n + 5
So we have that
an = n + 5
Where n is the term, that said we want the 1st, 2nd, 3rd, 4th and 10th term
a1 = 1 + 5 = 6
a2 = 2 + 5 = 7
a3 = 3 + 5 = 8
a4 = 4 + 5 = 9
a10 = 10 + 5 = 15
We would expect 2 people to come down with the flu.
We multiply the probability, 35%, by the number of people exposed, 5:
0.35*5= 1.75 ≈ 2
