Answer:

a+(n-1)d

Answer 2

Answer:

a= -1   d= -3   a12=?

we know that,  a(nth term) = a + (n-1)d

here                  a(12th term) = -1 + (12 - 1)(-3)

                                             => -1 - 33

                                             => -34

so the 12 th term of the AP is - 34
