Question

Prepare a flowchart and MATLAB program that will calculate

Q2: Fibonacci series is f1=1 f2=1 fn=fn-1+fn-2 (n>2) What is f20?

Answer 1

In Fibonacci series first term is 0 and 2nd term is 1.But as you have specified here that both f1 and f2 must be initialized to 1 I have written program accordingly.

Here the program below will print all numbers of Fibonacci series uptill the desired term.(Generalized program)

f1= 1;
f2 = 1;
n = input('Enter number of term desired');
for i = 1:n-2 %term for n
fprintf('\t')
fprintf('%d',f1);
f3 = f1 + f2;
f1 = f2;
f2 = f3;
end

In case you need only 20th term,then

f1 = 1;
f2 = 1;
n = input('Enter number of term desired');

for i = 1:18 %term for n
f3 = f1 + f2;
f1 = f2;
f2 = f3;
end

fprintf("%d",f1);

*Please ensure to do indentation of code written inside For loop properly ,because sometime when we submit answer from here it is automatically left aligned and indentation may be disturbed.we are looping till (n-2) because 1st and 2nd term(f1 and f2) have already been specified or initialized by us.
