Concept:The pattern involves a consistent cyclic shift of letters in the alphabet. Each letter is obtained by moving a fixed number of steps forward or backward from the previous one.Explanation:First, examine the given arrangement of letters. Identify the step size between consecutive letters. For instance, if the first letter is A and the next is C, the step is +2. Apply the same rule to all positions. Repeat the process to find the missing term. The missing letter fits the sequence exactly, following the same shift pattern. Verify by checking the relationship with adjacent letters. The pattern holds, leading to the correct letter.
