Find the next number in the following series:
11, 12, 20, 23, 33, 46, ?, ?
Although I like the
fibo solution I would like to emphasize the point that no series can be uniquely defined by presenting a number (huge as it may) of its members.
1, 2, 3 , 4 ,5 ... does not imply a(n)=n and the next member is not necessarily 6...!!
It could be inter alia 126 if a(n)=(n-1)*( n-2)*( n-3)*( n-4)*( n-5) +n
re :our series
I am free to assume a polynomial formula (5th degree since 6 numbers were given/ two numbers would give a linear form, 3 -quadratic etc).
AND a(7)= 2 a(8)=-255
AS GOOD AS ANY OTHER
