    The common difference in the arithmetic progression (AP) is -3. To find the term that is -81, we can use the formula: term = first term + (n – 1) * common difference. Solving for n, we get n = (term – first term) / common difference = (-81 – 21) / -3 = 34. No term in the given AP is 0 because the first term is 21 and the common difference is -3, so the terms are decreasing from 21.
