difference between two successive numbers in the series is constant and equals 4
4, 9, 14, 19, 24, 29, 34, 39, 44, 49
difference between two successive numbers in the series is constant and equals 5
5, 11, 17, 23, 29, 35, 41, 47, 53, 59
difference between two successive numbers in the series is constant and equals 6
4, 85, 1210, 1615, 2020, 2425, 2830, 3235
it's a combination of two different series the earlier digits of the series come from the multiplication table of 4 and the later digits come from that of 5. Also note that the series of 5 is starting from the second serial
like,
4 × 1 = 8
4 × 2 5 × 1= 85
and that way I got all these numbers
7, 149, 2118, 2827, 3536, 4245, 4954, 5663
this is also a combination of two series with earlier digits from table of 7 and the later from that if 9. here as well the series of 9 starts from from second serial
