Answer 1

i think B is the correct answer

Answer 2

Answer:

B) 2, 5/2, 3, 7/2

Step-by-step explanation:

For a sequence of numbers to be an AP,

2nd term - 1st term has to be equal to 3rd term - 2nd term

2nd term - 1st term=> 5/2 - 2 = 5-4/2 = 1/2--------------(i)

3rd term - 2nd term=> 3 - 5/2 = 6-5/2 = 1/2--------------(ii)

∵ (i)=(ii)

∴ The given sequence is an AP
