In this sequence there are actually two sequences. 1 sequence for the numbers in odd positions (1,3,5 enz) and one sequence for the numbers in the even positions (2,4,6 enz.) The following applies to the numbers in the odd positions:
You find the next number in the sequence by applying the following transformation: *3 and next to that also the following transformation: -10 Take a good look at the figure with the transformations!
VThe following applies to the numbers in the even positions:
In this sequence you find the next number by applying the following transformation: -2
