The given series is: 1, 5, 19, 77, 306, 1229, 4915

Let's try to find the pattern in the series:

1*4 + 1 = 5
5*4 - 1 = 19
19*4 + 1 = 77
77*4 - 1 = 306
306*4 + 1 = 1225 (not 1229)
1225*4 - 1 = 4900 (not 4915)

So, the wrong numbers in the series are 1229 and 4915. The correct series should be: 1, 5, 19, 77, 306, 1225, 4900.
