Odd/Even coding: Pos1:D→4, Pos2:E→E, Pos3:F→6 → 4E6
position, pattern, mixed

Question 2

If each letter is shifted forward by 1 positions (A→B), what is 'DOG' coded as?
Shift coding: D→E(+1), O→P(+1), G→H(+1) → EPH
shift, caesar, cipher

Question 3

If each letter is shifted forward by 4 positions (A→E), what is 'BOOK' coded as?
Shift coding: B→F(+4), O→S(+4), O→S(+4), K→O(+4) → FSSO
shift, caesar, cipher

Question 4

If A=2, B=3, C=5, D=7, E=11... (prime numbers in order), what is 'ABC' coded as?
Prime coding: A→2, B→3, C→5 → concatenated = 235

product, arithmetic

Question 9

If a word's code is the sum of its letter positions (A=1,B=2...), what is 'DOG's code?
Sum calculation: D=4 + O=15 + G=7 = 26
sum, arithmetic

Question 10

If A=26, B=25, C=24... Z=1 (reverse order), then 'BED' is coded as?
