Question

4. Write first four terms of A.P. whose first term is 2 and common difference is 3​

Answer 1

Answer:

here is your answer

Given as

a = -2 ( first term )

d = -2 ( Common difference)

As we know that

an = a + ( n - 1 ) d

As first term is - 2, to calculate 2nd term we will put n = 2

a2 = -2 + ( 2 - 1 ) -2

= -4

Now n = 3 to calculate third term

a3 = -2 + ( 3 -1 ) -2

= -6

Now n =4 to calculate fourth term

a4 = -2 + ( 4 -1 ) -2

= -8

Hence the first four term of AP is

-2 , -4, -6 and - 8

hope it helps

Answer 2

Answer:

a=2

d=3

1st term=2

2nd one is a+d

2+3=5

3rd one is a+2d

2+2(3)=8

4th one is a+3d

2+3(3)

11

First four terms are 2,5,8,11
