Tenth term

#### Explanation:

In an arithmetic sequence, the difference between acreen and its immediately preceding term is always constant. This is called as 'common difference'.

Let us check here. Here, we have

Hence, here we have an arithmetic sequence with first term

In an arithmetic sequence if first term is

Hence, tenth term in given sequence is
