Question

Verify the following sequence is A.P or not.
3/2 ,1/2 , -1/2 ,-3/2

Answer 1

Answer:

It is an AP

Step-by-step explanation:

3/2, 1/2, -1/2, -3/2

a1 a2 a3 a4

a2 - a1 = 1/2-3/2 = -2/2 = -1

a3 - a2 = -1/2-1/2 = -2/2 = -1

a4 - a3 = -3/2-(-1/2) = -3/2+1/2 = -2/2 = -1

a2-a1 = a3-a2 = a4-a3 = -1

It is an AP

Answer 2

Answer:

Yes, the sequence forms an A.P.

Step-by-step explanation:

To check if an A.P is correct, we need to check the difference between two consecutive terms of the A.P. If the difference is same in all the pairs then we can say that the the A.P is a correct one.

Second term - First term = 1/2-3/2 = -1

Third term - second term= -1/2-1/2 = -1

Fourth term-third term = -3/2-(-1/2) = -1

As the difference is same in all the pairs the A.P is correct.
