Verbal - "Number Series"

Example
4 6 8 10(?)
On the answer sheet you are given five numbers to choose from.
A8 B 10 C 12 D 20 E 16
With the sequence
4 6 8 10(?)
It is quite easy to see that the pattern is going up by 2 each time, therefore the next number in the sequence is 12, so the correct answer is answer option “C”.
4 -> (+2)-> 6 -> (+2)-> 8 -> (+2)-> 10 -> (+2) -> 12
