This question is very similar to a pervious perms and combs q on this website (I think involving coins?)Jessica is about to walk a flight 10 stairs. She can take either one or two stairs at a time. How many different ways can she walk up the flight of stairs?
The answer is 89, just not sure how
The person has to make a net movement of 10 steps to the left and 10 steps to the right. So this is basically just 20 steps in total with 1 or 2 steps so the answer is theThankyou very much Qeru, How about if it was in 2 dimensions, so like if a person could go 1 or 2 steps, and they had to go forward 10 steps, then right 10 steps
like fibonacci sequence number 21?The person has to make a make movement of 10 steps to the left and 10 steps to the right. So this is basically just 20 steps in total with 1 or 2 steps so the answer is theI think.
Yes I think solike fibonacci sequence number 21?
