Track letter positions independently: 1st letters move by -4, 2nd letters move by -2, and 3rd letters move by -2 across terms.
Track letter positions independently: 1st letters move by -4, 2nd letters move by -2, and 3rd letters move by -2 across terms.
Analyze Alternate Term Relations for 1st Letter
Looking at odd terms: 1st term O (15) and 3rd term M (13) give a difference of -2 (15 - 2 = 13). Looking at even terms: 2nd term A (1) and 4th term Y (25) give a difference of -2 (1 - 2 = -1 = 25 in cyclic alphabet). Following this alternate pattern, the 5th term's 1st letter comes from 3rd term M (13) - 2 = 11, which corresponds to 'K'.
Analyze Alternate Term Relations for 2nd Letter
Looking at odd terms: 1st term N (14) and 3rd term L (12) give a difference of -2 (14 - 2 = 12). Looking at even terms: 2nd term Z (26) and 4th term X (24) give a difference of -2 (26 - 2 = 24). Following this alternate pattern, the 5th term's 2nd letter comes from 3rd term L (12) - 2 = 10, which corresponds to 'J'.
Analyze Alternate Term Relations for 3rd Letter
Looking at odd terms: 1st term L (12) and 3rd term J (10) give a difference of -2 (12 - 2 = 10). Looking at even terms: 2nd term X (24) and 4th term V (22) give a difference of -2 (24 - 2 = 22). Following this alternate pattern, the 5th term's 3rd letter comes from 3rd term J (10) - 2 = 8, which corresponds to 'H'.
Combine Results to Form the Term
Combining the calculated letters for 1st, 2nd, and 3rd positions: K + J + H = KJH.
A: JKH has 'J' in the 1st position instead of 'K'. B: JHK has 'J' as 1st letter and 'H' as 2nd letter instead of 'K' and 'J'. D: KHJ has 'H' in 2nd position and 'J' in 3rd position, swapping the calculated letters.
C is correct because tracking the alternate series (1st тЖТ 3rd тЖТ 5th term) with a constant change of -2 for each letter position yields K (13-2=11), J (12-2=10), and H (10тИТ2=8), forming KJH.
When series jump drastically between adjacent terms (like O to A), immediately check the alternate terms pattern (1st to 3rd to 5th term), as alternate terms usually follow a straightforward -2 or -3 difference.
