Can anyone help with these two series:
1. What comes next: 1,111,10,121,11,12,?
2. What is the missing number: 4,8,6,18,15,60,56,280,?,1650
Thanks and happy new year
Ok Mark, how did you get 2 for the first one?
For the second one, the pattern is 2x,-2,3x,-3,4x,-4,etc.
I was only providing an answer to the second one. The "2." is the number of the problem.
The first one alternates between adding and subtracting numbers consisting of 0s and 1s. However, I don't see the pattern.
Stumble It!
