Hi Erik,
If you look at first 4 numbers, you will se that there was one increase
between first and second number (1 and 2), immediatly after that increase,
there is an increase between second and third number (2 and 3) and finaly
third consecutive increse between third and fourth number (3 and 4).
If you follow similar logic, you will identify that from 7th to 8th number
sequence decreased (from 6 to 5)...followed by 4 consecutive decreases
(until 12th and 13th number - from 2 to 1)...
Thanks for your time
