Given sequence: 28, 14, 14, 28, ?

Q.    Given sequence: 28, 14, 14, 28, ?

1.  Pattern: repeat every 4
28, 14, 14, 28 → cycle repeats → next = 28.
(Reason: the four-term block repeats.)

2.   Pattern: multiply factors 0.5, 1, 2, 4 (increasing multipliers)
28 → ÷2 → 14 → ×1 → 14 → ×2 → 28 → ×4 → 28×4 = 112.
(Reason: multipliers are 0.5, 1, 2, 4 — next gives 112.)

Best answer : 28, because the 4-term block 28, 14, 14, 28 repeats, so the next term is 28.
