How do you write a rule for the nth term of the arithmetic sequence and then find #a_10# for #-4, 2, 8, 14, 20#?
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
