Analyze the jump between terms: the first letter of each term increases by +6 consistently (A+6=G, G+6=M, M+6=S, S+6=Y, Y+6=E).
Analyze the jump between terms: the first letter of each term increases by +6 consistently (A+6=G, G+6=M, M+6=S, S+6=Y, Y+6=E).
Analyze the first letter progression
A(1), G(7), M(13), S(19), Y(25). The pattern is +6. Applying this to Y: 25+6 = 31. Since there are 26 letters, 31-26 = 5, which is E.
Analyze the second letter progression
C(3), I(9), O(15), U(21), A(1). The pattern is +6. Applying this to A: 1+6 = 7, which is G.
Analyze the third and fourth letter progression
Third letters: D(4), J(10), P(16), V(22), B(2). Pattern +6. 2+6 = 8, which is H. Fourth letters: F(6), L(12), R(18), X(24), D(4). Pattern +6. 4+6 = 10, which is J. Combining these gives EGHJ.
A: EGFJ is incorrect as the third letter should be H; C: EGIK is incorrect as the third and fourth letters do not match the +6 pattern; D: EFHJ is incorrect as the second letter should be G.
B is correct because the series follows a consistent +6 increment for every letter position, resulting in E(5), G(7), H(8), J(10).
When dealing with multi-letter series, solve one position at a time (first letter, then second, etc.) to isolate the pattern and avoid confusion.
