Concept:
Analyze the first and second letters separately.
Step 1: Study the first letters.
\[
C,\ E,\ G,\ K,\ M,\ Q
\]
Alphabetical positions:
\[
3,\ 5,\ 7,\ 11,\ 13,\ 17
\]
These are consecutive prime numbers.
The next prime is
\[
19,
\]
which corresponds to
\[
S.
\]
Step 2: Study the second letters.
\[
W,\ U,\ S,\ O,\ M,\ I
\]
Positions:
\[
23,\ 21,\ 19,\ 15,\ 13,\ 9
\]
The pattern decreases by 2, 2, 4, 2, 4,...
Continuing,
\[
9-2=7.
\]
The \(7^{th}\) letter is
\[
G.
\]
Step 3: Combine the results.
First letter:
\[
S
\]
Second letter:
\[
G.
\]
Hence the required term is
\[
\boxed{SG}.
