Find the indicated term of each arithmetic sequence a(1)=14, d=9, n=11

The first term of an arithmetic sequence is 14, that is:

. Also, we are given that the common difference is 9, which means that each next term is obtained by adding 9, as follows:

.

So we notice that to get the value of the n'th term, , we must add (n-1) nines to 14.

(For example, to find the second term we added 1 nine to 14. To find the third term we added 2 nines to 14, and so on...)

Thus, 

104.
