How to find the nth term of the series 30,35,38,41,54,53,78,71,110.........

Answer 1

Answer:

when you look at the difference between each numbers

5 3 3 13 -1 25 -7 39 -15

so when you take the alternate numbers(1st 3rd 5th...) you can see a pattern of -2

when you look at the alternating digits from the 2nd number(2nd 4th 6th...)you can see a pattern of +10,+12,+14..

hope you can get it now :)
