Question

Write the first four terms of an ap whose first term is -2 and common difference is (-2)

Answer 1

Answer:

-2,-4,-6,-8

Step-by-step explanation:

-2+-2=-4

-4+-2= -6

-6+-2= -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,..........
