Find the missing term in the series: B, C, E, H, L, ?
M
N
O
Q
Q
Convert letters to their numerical positions (A=1, B=2, etc.) and observe the increasing gap between consecutive terms (+1, +2, +3, +4, +5).
Convert letters to their numerical positions (A=1, B=2, etc.) and observe the increasing gap between consecutive terms (+1, +2, +3, +4, +5).
Mapping letters to positions
Convert each letter in the series to its corresponding alphabetical position: B=2, C=3, E=5, H=8, L=12.
Identifying the numerical difference
Calculate the differences between consecutive terms: 3-2=1, 5-3=2, 8-5=3, 12-8=4.
Calculating the next term
The pattern of differences is +1, +2, +3, +4. Therefore, the next difference must be +5. Adding 5 to the last term (12) gives 12 + 5 = 17.
Final conversion to letter
The 17th letter in the English alphabet is Q.
A: M is the 13th letter, which would require a difference of +1; B: N is the 14th letter, which would require a difference of +2; C: O is the 15th letter, which would require a difference of +3.
D is correct because the difference between consecutive terms increases by 1 each time (1, 2, 3, 4, 5), and 12 + 5 results in 17, which corresponds to the letter Q.
Whenever you see an alphabet series, write down the numerical position of the letters immediately; this often reveals hidden arithmetic patterns that are hard to spot otherwise.
