The following question given below shows the series I and series II with different logics
Series I: 315, 350, 393, 435, 479, 525, 573.
Series II: a, c, d, 350, e, f, b
If the wrong number in series I is the middle number of the series II and the pattern from series I is continuing to series II, the ending logic of the series I is the beginning logic of the series II. Find (a + b)
