Question

Write the common difference of the ap whose nth term is given by tn equal to 6n + 2

Answer 1

Hi the general form of nth term of an AP is
$a + (n - 1) \times d$
where a is the first term and d is the common difference.
To find d of given nth term, convert it into general form as below
$6n + 2 \\ = 6(n - 1) + 8$
Therefore d=6 and a= 8
