Find the 66th term of the arithmetic sequence 3, 13, 23, ... 3,13,23, ...

653

Step-by-step explanation:

I will need to assume that you meant 3, 13, 23, 33, 43, ...

Here the first term is 3 and the common difference is 10. The formula is a (n) = 3 + 10 (n-1)

Thus, the 66th term is 3 + 10 (66-1), or 3 + 10 (65), or 653.
