Two chemical solutions, one containing N molecules of chemical A and another containing M molecules of chemical B, are mixed together at time t = 0. The molecules from the two chemicals combine to form another chemical solution containing y (AB) molecules. The rate at which the AB molecules are formed, 
, is called the reaction rate and is jointly proportional to ![]()

Find anand a6 for the following arithmetic sequence.a1 = -50, d = -3
A. an = -50 + 3n, a6 = -32 B. an = -50 - 3n, a6 = -68 C. an = -50 - 3(n - 1), a6 = -65 D. an = -50 + 3(n - 1), a6 = -35
