	spoiled in more detail than .1:


>>	1    1    1    4    27    3125    ...

	 0    1    1    2    3      5
	0    1    1    2    3      5

			  f(n)
	The series is f(n)     where f(n) is the nth Fibonacci
	number.

				8
	So the next element is 8  or 262144.

1107.3Too easy, I suppose.....ARTMIS::MILLSHand 50g scepticism, at gas mark 4....Fri Aug 11 1989 05:4014
	Well done! 
	You got it, so what is the exact numerical value of the next element
	after that?

	Also - There is an error in .2

		 8
	I think 8  is usually taken to be 16777216.

	Oops, I only typed in six of them to DCL. :-)

		$ write sys$output 8 * 8 * 8 * 8 * 8 * 8
		262144
