An infectious disease spreads slowly through a large population. Let Q(t) be the proportion of the
population that has been exposed to the disease within t years of its introduction. If
Q'(t) = 0.15[1 – Q(t)]
and Q(0)=0, then applying the Forward Euler formula with a step size of h=1 to estimate Q(i), for
i=1,...,5, yields:
$(1) - Q1 =
