General term for an arithmetic sequence is given by $a_n=a_1+(n-1) d$ See below.
General term for an arithmetic sequence is given by $a_n=a_1+(n-1) d$ Here, $a_1 \to$ Inital Term and $d=$ Common difference. The General term for an arithmetic sequence is given by $a_n=a_1+(n-1) d$ and this can be obtained by adding the initial term to the product between the $d$ and the number with an unit lower than the position in the sequence.
