(a) JS28
Steps to Solve
- Analyze the pattern in the first letters
The first letters are B, D, F, H. These are the 2nd, 4th, 6th, and 8th letters of the alphabet, respectively. The pattern is to add 2 to the position of the previous letter. So, the next letter should be the 10th letter of the alphabet, which is J.
- Analyze the pattern in the second letters
The second letters are J, L, N, P. These are the 10th, 12th, 14th, and 16th letters of the alphabet, respectively. The pattern is to add 2 to the position of the previous letter. So, the next letter should be the 18th letter of the alphabet, which is R.
- Analyze the pattern in the numbers
The numbers are 12, 16, 20, 24. The pattern is to add 4 to the previous number. So, the next number should be $24 + 4 = 28$.
- Combine the results
Combining the next letters and number, the next element in the sequence is JR28. However this is not one of the answer choices, we made an error in previous steps The correct second letters are J, L, N, P So the next letter must be R And the pattern is JR28
- Final Answer
Comparing with the available answer choices, JS28 is the closest answer
(a) JS28
More Information
