Treasure hunt question

A series of numbers is given in the question and it could be anything. Have tried things related to temperature values etc. but none worked.

Guessing the next number in this series looks highly unlikely.

16 18 20 62


Hint: Answer is a 7 letter word.

• +2, +2, +2, +22, +22, +22, +222... probably 84 with my logic – Anthony Pham Mar 6 '16 at 17:45
• Thanks for the reply. But this didnt work – Mitaksh Gupta Mar 6 '16 at 17:47
• Looks like this isn't a mathematic series question. Maybe something which these numbers represent. – Mitaksh Gupta Mar 6 '16 at 17:49
• Can you give us the whole question? – bleh Mar 7 '16 at 0:50
• @bleh this is the entire question. Only these numbers are given. We need to figure out what they represent. – Mitaksh Gupta Mar 7 '16 at 2:31
