You could literally say that 20 is the number that does not belong because all of the rest are minus values BUT 370 would also be correct because it contains the number 3 which is the only number in the entire sequence 204070100160220290370460 which does not repeat itself except nine but the non-repeating number in 370 is next to a number only repeated once whereas 9 in 290 is next to 2 numbers which repeat more than once.
