Answer:
An arithmetic sequence is a sequence that has the property that the difference between any two consecutive terms is a constant. This constant is called the common difference. If \displaystyle {a}_{1}a
1
is the first term of an arithmetic sequence and \displaystyle dd is the common difference, the sequence will be:
{
a
n
}
=
