Oh, I love those sequences which are usually in every IQ-Test.

1,2,3,5,8,13,21,34,55

This is the Fibonacci-Sequence which always adds the last 2 numbers in every step.

1,4,9,16,25,36,49,64,81

These are the natural numbers, but squared.

So here I bring 2 new ones, which are the next 2 numbers?

65536, 256,...

5, 6, 12, 9, 10, 20, 17,...

65536, 256, 16, 4, The next number in the sequence is found by taking the square root of the previous number.

5, 6, 12, 9, 10, 20, 17, 18, 36, 33, ... The pattern for this sequence is add 1, multiply by 2, and subtract 3.

Yes, you are totally right. In the first sequence you could have also choose a few other options like:

65536,256,1,1/256 or
65536,256,-65024,-130304 or
2^16,2^8,2^4,2^2 or
2^16,2^8,2^0,2^-8

due to the fact that I showed only the first 2 numbers.

 11-12-2014 #7 Dragonballful23     Join Date: Dec 2011 Posts: 386 Since this thread is about sequences, I guess i will create more. Find the next 2 numbers for this one: 1,2,3,9,10,11,12,18. For this one find the 99th term in the sequence. 1,5,25,20,100,500,495 __________________ Finally finished all my tests!!!
