Show the answer and explanation
CorrectNot quiteAnswer C
Correct answer: C
Explanation
C = 24, A = 26, R = 9: these are reverse positions (Z = 1, A = 26), found as 27 minus the position.
To decode, subtract each number from 27: , , , .
20, 15, 12, 4 are T, O, L, D. The word is TOLD.
Worth noting
GLOW reads the numbers as ordinary positions. It is a real word, which makes it tempting, but that reading would code CAR as 3-1-18.
