Show answer & explanation

Correct answer: C

  • Analyze the first letter of each cluster: C (+4) = G, G (+4) = K, K (+4) = O, O (+4) = S. Next is S + 4 = W.

  • Analyze the second letter: G (+4) = K, K (+4) = O, O (+4) = S, S (+4) = W. Next is W + 4 = A.

  • Analyze the third letter: K (+4) = O, O (+4) = S, S (+4) = W, W (+4) = A. Next is A + 4 = E. The pattern is simply taking the last two letters of the previous cluster and adding 4; S-W-A is the correct sequence.
