Input:
nterms = as.integer(readline(prompt="How many terms? ")) # first two terms n1 = 0 n2 = 1 count = 2 # check if the number of terms is valid if(nterms <= 0) { print("Plese enter a positive integer") } else { if(nterms == 1) { print("Fibonacci sequence:") print(n1) } else { print("Fibonacci sequence:") print(n1) print(n2) while(count < nterms) { nth = n1 + n2 print(nth) # update values n1 = n2 n2 = nth count = count + 1 } } }
Out put:
How many terms? 6 [1] "Fibonacci sequence:" [1] 0 [1] 1 [1] 1 [1] 2 [1] 3 [1] 5
