Which of the following methods can be used to construct a pattern of 10 numbers for which it would be mathematically impossible to predict the 11th term?
(more then one answer.)
A.Make a pattern, starting with 3, where each number is the next digit of pi (3.14159 . . .).
B.Make a pattern by asking each of 10 friends what their favorite number is.
C.Make a pattern by counting the number of letters in each word of Lincoln's Gettysburg Address, starting with the first word.
D.Make a pattern based upon values assigned to the current weather.
E.Make a pattern where each number is the square of the number before it, plus 7 times the cube of the number before that.
I'd say B and D, subject to a few assumptionsposted by Steve
