How do nth terms work?

To work out the nth term, we first must work out the common difference, and then we look at how we make the common difference equal one of the terms in the sequence. When n=1, 3n=3, which is not a term in our sequence. If we subtract 1,we get 2, which is a term in our sequence! So, the nth term is “3n-1”.

What is the 10th term of Fibonacci sequence?

the tenth Fibonacci number is Fib(10) = 55. The sum of its digits is 5+5 or 10 and that is also the index number of 55 (10-th in the list of Fibonacci numbers). So the index number of Fib(10) is equal to its digit sum.
