Sorry to use a second answer here, the discussion is now pretty big.
Dear lecturer, tell me if I am right or wrong.
Your alien lays 3 eggs on day 1.
-If the eggs hatch on same day. On which day will they hatch ? My answer is day 1.
-If the eggs hatch 1 day after. On which day will they hatch ? My answer is day 2.
-If the eggs hatch 2 day after. On which day will they hatch ? My answer is day 3.
-If the eggs hatch 3 day after. On which day will they hatch ? My answer is day 4.
-If the eggs hatch 4 day after. On which day will they hatch ? My answer is day 5.
-If the eggs hatch 5 day after. On which day will they hatch ? My answer is day 6.
I guess everyone agree on this list :)
You posted this as a part of the solution:
Quote:
day 1 1 alien 3 eggs
day 2 1 alien 6 eggs
day 3 1 alien 9 eggs
day 4 1 alien 12 eggs
day 5 4 aliens 21 eggs
day 6 7 aliens 39 eggs
From this sequence, one can see that eggs laid on day 1 are hatching on day 5, which is after 4 days, when the problem state after 5 days.
PS: defeat not accepted because we all know you are wrong and infinite arguing have no interest. :-)

what don't you understand about every FIFTH day ,
there is nothing to understand there because it is not the question. :)
The question is:
Quote:
An alien lays X egg each day and the eggs hatch after Y days.
If X is 3 and Y is 5, how many aliens
and "after 5 days" is not the same as on "fifth day".
