The correct answer is

KGC 39

The numeric part decreases by 12 each time: 87, 75, 63, 51, so the next number is 39.

For the letters, tracking each position separately: the first letters go E, Z, U, P — a jump of +21 then steady drops of −5, giving the next letter K.

The second letters go A, V, Q, L — the same pattern gives the next letter G.

The third letters go W, R, M, H — dropping by 5 each time gives the next letter C.

Combining, the next cluster is KGC, and with the number 39, the answer is KGC 39.
