Select the option that can replace the question mark (?) in the following series.

L34E, O46H, R58K, U70N, ?

Solution

Let's analyze the given series: L34E, O46H, R58K, U70N, ? The pattern appears to be: The first letter of each group follows the sequence L, O, R, U, ... (incrementing by 3 each time). The numbers in between increase by 12 each time: 34, 46, 58, 70. The last letter of each group follows the sequence E, H, K, N, ... Following this pattern, the next letter should be X (U + 3), and the number should be 82 (70 + 12). So, the missing term is X82Q. Therefore, the correct option is 1. X82Q
