P41= P, x ezp (r x (1–)
where: exp (x) = ez
Here is a simple R program that implements the Ricker model
pops<-c)
r<-0.05
K<-1000
pop<-100
for (i in 1:200){
pops[i]<-pop
pop<-pop*exp(r*(1-pop/K))
plot(pops,type="I")

What is the population at the 50th timestep? You can get this by
looking at the value of the 50th entry in the pops vector:
pops[50]
50
100
150
200
000
008
009
007
