In an A.P., if the common difference (d)=-4 and the seventh term `(a_7)` is 4 then find the first term

In an A.P. the common difference (d) is 6 and seventh term is 36. Can we write such an A.P.?

If the first term a_(1) of an A.P. is 22, the common difference d=-4 and the sum to n terms is 64, find n. Explain the double answer.

If the first term a_1 of an A.P. is 22, the common difference d = -4 and the sum to n terms is 64, find n. Explain the double answer.
