Answer 1

You are using i for iteration

It is giving more terms because

You have already printed 2 terms

So you need to subtract 2 from terms

And i must be less than terms -2 because i is starting from 0

So write

i < terms - 2
as your condition in while loop

Answer 2

Sir you method worked but for i <= terms-3 . Please tell me why -3 and you said for -2 . And thanks you for helping me ☺️

Answer 3

i working as a counter initial i =0;
and in while(i<=term)
and each time i is increasing and condition will be false when i<=term will be false

Answer 4

Yeah you can -3 as well

For example

You entered 1, 1
Terms = 5

1, 1, 2, 3, 5 // it has 5 terms

So if you write

i <= terms - 3
Then only you will be able to print the above series

Reason:

Just note carefully you have already input 1, 1

Which means you already have 2 terms in the beginning. Now you need to find 3 more terms

Why?
Because Terms = 5 // as entered

So for finding rest of the 3 terms you need to run the while loop only 3 times

But if you write i <= terms
Your while loop will runs 6 times. because i = 0
And you will have 3 extra terms in your output ( 5 + 3 = 8 terms)

But we need only 5 terms not 8
Because we entered terms = 5

So that's why you need to subtract -3 as per your code because your condition was i <= terms

But I subtracted -2 because
My condition was i < terms - 2

I did not used the = operator

Both of us are correct
