Select the letter cluster that is related to the third cluster in the same way as the second cluster is related to the first cluster.
PTK : RWO :: SUW : ?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → UXA
Compare each letter of the first cluster with the letter in the same place of the second, using places in the alphabet; after Z the count continues from A.
P (16) to R (18) is 2 places, T (20) to W (23) is 3 places, K (11) to O (15) is 4 places, so the shifts are +2, +3, +4
S (19) moves to \(19+2=21\), U
U (21) moves to \(21+3=24\), X
W (23): 4 places ahead are X, Y, Z, A, so W moves to A
So the missing cluster is UXA.
