In a certain code language, the word "REASON" is encoded as TDDQSK. Using the same rule, how is the word PRAYER coded?

Solution

Given: "REASON" is coded as "TDDQSK". 
 Write positions of letters (A=1, B=2, ..., Z=26): 
 R(18) → T(20): +2 
 E(5) → D(4): −1 
 A(1) → D(4): +3 
 S(19) → Q(17): −2 
 O(15) → S(19): +4 
 N(14) → K(11): −3 
 So the rule is: +2, −1, +3, −2, +4, −3 (alternating + and −, with magnitude increasing). 
 Now apply same rule to "PRAYER": 
 P(16) +2 → R(18) 
 R(18) −1 → Q(17) 
 A(1) +3 → D(4) 
 Y(25) −2 → W(23) 
 E(5) +4 → I(9)
 R(18) −3 → O(15) 
 Hence, "PRAYER" is coded as: RQDWIO.
