The first term is (for x = 1) = 10
The explicit equation is y = 3x + 7
With the help of explicit formula, we can get any term my using the different values of x.
For example, if we put x = 1, we can get the first term.
y = 3x + 7
y = 3(1) + 7
y = 3 + 7
y = 10 (That is exactly the first term.)
Similarly, we can get the 9th term by placing x = 9. So,
y = 3(9) + 7
y = 27 + 7
y = 34
Therefore, the 9th term would be 34.
