Question

2. The first four terms of an AP, 1 point
whose first term is -2 and the
common difference is -2, are
​

Answer 1

Step-by-step explanation:

t4=a+(n-1)d

t4=-2+(4-1)(-2)

t4=-2-6

t4=-8 is the answer of this question

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,..........
