Answer 2

The first four terms of an A.P. is -7 , -4 , -1 , -2

Step-by-step explanation:

GIVEN

First term = -7

Common difference = 3

___________________________

To Find

The first four terms of an A.P.

___________________________

Finding t2

We know that,

Common difference = t2 - t1 = 2nd term - 1st term

3 = x - (-7)

x = -7 + 3

x = -4

T2 = -4

2nd term is -4

___________________________

Finding t3

We know that,

Common difference = t3 - t2 = 3rd term - 2nd term

3 = x - (-10)

x = -4 + 3

x = -1

T3 = -1

3rd term is -1

___________________________

Finding t3

We know that,

Common difference = t4 - t3 = 4th term - 3rd term

3 = x - (-13)

x = -1 + 3

x = 2

T4 = 2

4th term is 2

The first four terms of an A.P. is -7 , -4 , -1 , 2
