MediumOriginal questionWhich term continues the series C6, F12, I18, L24, ?
Show the answer and explanation
CorrectNot quiteAnswer B
Correct answer: B
Explanation
Letters: C, F, I, L are positions 3, 6, 9, 12, so the next is 15, which is O.
Numbers: 6, 12, 18, 24 go up by 6 (each is twice its letter's position), so the next is 30.
The next term is O30.
Worth noting
P30 and N30 get the number right but miss the letter by one; count positions (EJOTY: O is 15), do not count on your fingers.
