Which one of the letters does not belong in the following series: D - F - H - J - K - N - P - R.

Solution:

The series D - F - H - J - K - N - P - R represents the alternate letters.

The sequence and series are the orderly arrangements of numbers or alphabet under a specific rule.

We observe that the letters used are alternate letters and that the letter K does not belong to this series.

For example, The immediate letter that comes after D is E but the series has F which is alternate.

Similarly, the letter I comes after H but the series has J.

Therefore, K does not belong to the series as it occurs immediately after the letter J

Which one of the letters does not belong in the following series: D - F - H - J - K - N - P - R.

Summary:

The letters in the series D - F - H - J - K - N - P - R are alternate but K is immediate.
