I think it is 20
(6 x 3) + 4 = 22
(22 x 3) + 4 = 70
(70 x 3) + 4 = 214
(214 x 3) + 4 =646
(646 x 3) + 4 = 1942
(1942 x 3) + 4 = 5830

It is 20. The series runs like this: (Previous number x 3) + 4 = Next number in the series. Hence (6 x 3) + 4 = 22 and not 20. Again (22 x 3) + 4 = 70, which makes it a series thereafter. But (20 x 3) + 4 = 64 and not 70. So the series breaks here too. (70 x 3) + 4 = 214; (214 x 3) + 4 = 646 and so on. So the answer is 20, which should be replaced by 22.

The answer is 20 because in this series the concept is that you are multiplying the previous number by 3 and then adding four to the result to get the next number of the series.
6*3 +4=22 and 22*3 +4=70
So instead of 20 in the series, there should be 22. The odd number in the series is 20.

The second number should be 22.
The key to the series is to multiply each number by 3, then add 4.
6 x 3 + 4 = 22
22 x 3 + 4 = 70
70 x 3 + 4 = 214
etc
