Is the pattern 1 6 4 9 7 12 10 recursive?

Answer 1

Oh honey, that pattern is about as recursive as a goldfish trying to climb a tree. No, darling, there's no clear mathematical relationship or pattern to be found here. It's like trying to find meaning in a Kardashian's Instagram post - just a whole lot of randomness.

Answer 2

It can be written recursively as follows:

U1 = 1

U2 = 6

U3 = 4

Un = Un-1 + Un-2 - Un-3 for n ≥ 4
