Now we have the sequence
4,7,10,13,16,19,22,25
for the
1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th term.
Tn=3n+1 for any nth term (I found this by trial and error, messing around with the terms)
You can double check this
for the 3rd term, T3=3(3)+1=10, correct
for the 7th term, T7=3(7)+1=22. correct.
So you want to find
100=Tn
So using our formula, Tn=3n+1
100=3n+1
99=3n
33=n
Therefore the 33rd term is equal to the 100th term.
