In the given problem, we need to write the first term (a) and the common difference (d) of the given A.P
(i) −5, −1, 3, 7 …
Here, first term of the given A.P is (a) = −5
Now, we will find the difference between the two terms of the given A.P
Therefore, the first term of the given A.P is and the common differenc...
