Find the odd one out in the given sequence.
1296, 648, 216, 108, 34, 18
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 34
Each term is the one before it divided by 2 and by 3 in turn:
\(1296\div2=648\)
\(648\div3=216\)
\(216\div2=108\)
\(108\div3=36\), but the series shows 34
\(36\div2=18\), which agrees with the last term
The fifth term should be 36, so 34 is the odd one out.
