Explanation:
Detailed explanation-1: -The formula for the nth term is given by: Tn = a + (n − 1)d = dn + (a − d) (2) where a and d are fixed and n is the variable (integer ≥ 1). This corresponds to y = mx + b where m and b are fixed and x variable.
Detailed explanation-2: -Hence, the sum of the given terms is 610.
