Question

the first four terms of ap, whose first term is-2 and common difference is -3 are​

Answer 1

Answer:

1st term= -2

common difference= -3

2nd term= -2+(-3)= -2-3= -5

3rd term= -5-3= -8

4th term = -8-3=. -11

so, the first four terms of ap are -2 , -5 , -8 , -11

Answer 2

Answer :-

The first four terms of A.P. are -2, -5, -8 and -11.

Step-by-step explanation

To Find :-

• The first four terms of A.P.

Given that,

• First term = -2
• Common difference = -3

As we know that,

✧ t₁ = a

✧ t₂ = a + d

✧ t₃ = a + 2d

✧ t₄ = a + 3d

Where,

a = First term

d = Common difference.

t = term

According the question,

→ t₁ = a = -2

→ t₂ = a + d = -2 + (-3) = -5

→ t₃ = a + 2d = -2 + 2(-3) = -2 + (-6) = -8

→ t₄ = a + 3d = -2 + 3(-3) = -2 + (-9) = -11

Hence,

t₁, t₂, t₃ and t₄ = -2, -5, -8 and -11.

Verification

Let's check whether the answer is correct or not?

We can check the answers by calculating the common difference.

In the question, it's given

Common difference = -3

So,

→ -2 + -3 = -5

→ -5 + -3 = -8

→ -8 + -3 = -11

Hence, Verified!
