A333
B166
C223 ✓ Correct
D222
Correct answer: (C) 223 — The answer is 223.
Explanation
★The answer is 223.
★Each term is got by doubling the previous term and adding 1.
★So 6 gives 13, 13 gives 27 and 27 gives 55.
★Then 55 gives 111.
★Doubling 111 and adding 1 gives 223.
★The other options do not fit this rule.
★So the answer is 223.
