Question

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

Answer 1

Answer:

-2, -4, -6 ,-8

Step-by-step explanation:

Using a(n) = a + (n-1) d

HERE n = 1,2,3,4

d = -2

a1 = -2

a2 = -4

a3 = -6

a4 = -8

Answer 2

Given :

• First term (a) = -2

• Common Difference (d) = -2

______________________

To Find :

• Four terms of AP

______________________

Solution :

⇒a = -2

____________

⇒a2 = a + d

⇒a2 = -2 - 2

⇒a2 = -4

____________

⇒a3 = a + 2d

⇒a3 = -2 + 2(-2)

⇒a3 = -2 - 4

⇒a3 = -6

____________

⇒a4 = a + 3d

⇒a4 = -2 + 3(-2)

⇒a4 = -2 -6

⇒a4 = -8

So, AP is -2,-4,-6,-8,..........
