The given sequence is a combination of three series.
I – 2, 4, 6, 8 these are 1st, 4th, 7th, 10th term II — 1,4,7, 10 these are 2nd, 5th, 8th, 11th term III—32,5,8, 11 these are 3rd, 6th, 9th, 12th term
Clearly, I consists of consecutive even numbers and it is the term from that series which has to come next, thus 10.
