The first four terms of an AP, whose first term is –2 and the common difference is –2, are – 2, – 4, – 6, – 8. Explanation: First term, a = – 2 Second term, d = – 2 a1 = a = – 2 We know that the nth term of an AP is an = a + (n – 1)d Where, a = first term an is nth term d is the common difference Hence, we have, a2 = a + d = – 2 + (– 2) = – 4 Similarly, a3 = – 6 a4 = – 8 So the A.P is – 2, – 4, – 6, – 8.
