Concept:The pattern is a continuous alternating sequence of +1 and +2 shifts, carried over from the previous word.
Explanation:In ARGOT → BTHQU, the shifts are: A→B (+1), R→T (+2), G→H (+1), O→Q (+2), T→U (+1).
The sequence ends with a +1 shift.
For BARON, continue the alternating pattern starting with the next shift: +2, +1, +2, +1, +2.
Apply to BARON: B+2 = D, A+1 = B, R+2 = T, O+1 = P, N+2 = P → DBTPP.
