Find the missing group of alphabets in the following series.
ZC, AI, (…), KI, PL
Correct Answer:
D. FV
Explanation:
To solve this alphabet series, we analyze the progression of the first and second letters in each group separately to identify the underlying pattern. Analyzing the First Letters: The first letters are Z, A, (?), K, and P. - Z is the 26th letter and A is the 1st. In a cyclic alphabet, moving from Z to A is a jump of +1. - Examining the gap between K (11th) and P (16th), we see an increase of 5 positions. - Applying a consistent +5 increment starting from A (1st letter): 1 + 5 = 6. The 6th letter is F. - Testing this against the next term: 6 + 5 = 11, which matches K. Therefore, the first letter of the missing group is F.Analyzing the Second Letters: The second letters are C, I, (?), I, and L. - From C (3rd) to I (9th), there is an increase of 6. - From I (9th) to L (12th), there is an increase of 3. - Given the options provided, we look for a pair starting with F. Among the choices (MO, EZ, SV, FV), only FV begins with the letter F. - In the group FV, V is the 22nd letter. Following a pattern of +6, +7, then resetting or adjusting based on the cycle: 9 (I) + 13 = 22 (V), and 22 (V) + 13 = 35. Subtracting the 26 letters of the alphabet gives 9, which matches the second I in the series.Conclusion: By identifying that the first letter must be F to maintain a consistent mathematical progression (+5) between the known terms, we can determine that FV is the correct missing group.
