in this series 1st term is 5 and common difference is 3
let the last term is n'th term
so, 5+(n-1)×3=95
=>n=31
so the last term is 31st
let the last term is n'th term
so, 5+(n-1)×3=95
=>n=31
so the last term is 31st

1st = 5
2nd = 8
3rd = 11
4th = 14
See the pattern?
As you can now see, the numbers are related to the order that they are in. The pattern is x 3 + 3 so to figure out the answer which is
(95 - 3) divided by 3 will equal to 30.67
That can be rounded down (has to be down) to thirty
The answer is thirty
