Which one number is wrong in the given series. 4 5 - 4 25 - 28 53

The pattern: each term equals the sum of the two preceding terms. Starting with 4 and 5: 4+5=9, 5+(-4)=1, (-4)+9=5 (should be 25), 9+5=14, 5+14=19. The pattern breaks at 25 - it should be 5, not 25. Alternatively, if treating it as alternating signs: 4, 5, -4, 25, -28, 53 doesn't fit clear alternating rules. 25 is the most likely outlier.
