What comes next?
RST, STU, TUV, UVW, VWX, WXY, XYZ, YZA, ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ZAB.
Given series: RST, STU, TUV, UVW, WXY, XYZ, YZA, ?
R + 1 = S, S + 1 = T, T + 1 = U, U + 1 = V, V + 1 = W, W + 1 = X, X + 1 = Y, Y + 1 = Z
S + 1 = T, T + 1 = U, U + 1 = V, V + 1 = W, W + 1 = X, X + 1 = Y, Y + 1 = Z, Z + 1 = A
T + 1 = U, U + 1 = V, V + 1 = W, W + 1 = X, X + 1 = Y, Y + 1 = Z, Z + 1 = A, A + 1 = B
