These 12 elements form a set with a certain pattern, but there is one element that does not fit. Which one is that?
The pattern is similar to this pattern having twelve elements too: 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35
There is a rule in the two distinct but similar patterns. For the number pattern it is: "3n+2".
The rule is not exactly the same in the letter set, but the item that breaks the pattern has a correspondence (one on one logical correspondence) in the number set.
