COMMENTS
For smaller values of n a maximum value of 1385 is common; this is similar to the value 9232 for the standard Collatz map. See A025586.
A graph of the terms looks similar to those of A336957 and A098550. See the linked image.
EXAMPLE
a(6) = 160 as the map A350805(6) gives 6 -> 11 -> 34 -> 53 -> 160 -> 21 -> 32 -> 5 -> 16 -> 4 -> 2 -> 1, the maximum value of which is 160.
