Assuming that you mean that multiple letters are missing...
manoeuvre
outmanoeuvre
moviemaking
moviegoing
moviehouses
(I'm sure there are more)
J S U N P [P may or may not be there]
v
y
the next letter would be 'b'
u n p
m
J = Jupiter planets outward from Sun MVEMJSUNP
N Neptune planets out from Sun E is Earth, for example
The next letter in the sequence is S. The sequence follows the pattern of skipping every other letter in the alphabet, starting with C.
N for november. The sequence starts with march.
The next letter in the sequence is M. The sequence follows the alphabetical order with a pattern of skipping letters.
it's very simple, i think you didnt think at all :) it is letter S
n for November
As I interpreted it, the sequence is the first letter of 4 months in chronological order, January February March April So therefore the next letter would be M for May.
