Q5 of 89 Page 45

The first four terms of an AP whose first term is - 2 and the common difference is - 2 are

First term, a = - 2


Second Term, d = - 2


a1 = a = - 2


a2 = a + d = - 2 + (- 2) = - 4 (using formula an = a + (n - 1)d)


similarly


a3 = - 6


a4 = - 8


so A.P is


- 2, - 4, - 6, - 8
