The correct answer is

NLO

The given series is: IGT, JHS, KIR, LQJ, MKP, ?. To find the missing term, observe the pattern in each set of letters.

First Letter: Observe the pattern among the first letters: I, J, K, L, M. Here, the sequence is alphabetical and each next letter is the successive English alphabet letter. Hence, the letter after M is N.

Second Letter: The sequence for second letters is: G, H, I, Q, K. Let's find a pattern. The difference between the ASCII values: H (72) - G (71) = 1, I (73) - H (72) = 1, Q (81) - I (73) = 8, K (75) - Q (81) = -6. The pattern doesn't have an apparent rule, but the pattern repeats, skipping the sequence of English letters, so the letter after K should be L to maintain the alphabetical alignment across unexplained jumps.

Third Letter: The sequence for the third letters: T, S, R, J, P. The difference between the ASCII values: S (83) - T (84) = -1, R (82) - S (83) = -1, J (74) - R (82) = -8, P (80) - J (74) = +6, this suggests a pattern with consistent and larger steps, notably returning backwards then forward, correlating with a deduction from P logically reaching to O if linear back stepping is omitted.

Thus, the missing term that completes the series is NLO.
