In the given question, choose the term that is odd one out from the given set. F1, H5, J10, L16, N23, Q30, R40

Analyze the pattern of letters and numbers separately. Letters: F(6), H(8), J(10), L(12), N(14), Q(17), R(18). They mostly increase by 2: 6,8,10,12,14... then 17 (should be 16/P), then 18. So Q is the odd one out as it breaks the +2 pattern. Numbers: 1, 5, 10, 16, 23, 30, 40. Differences: +4, +5, +6, +7, +8, +10. The difference between 30 and 40 is +10, but it should be +9 (after +8). This also points to the last term, but the question asks for the odd term, which is Q30 based on the letter sequence.
