Question

Example 2 : Which of the following list of numbers from an AP? If they form an AP, write the next two terms :
(i) 4,10,16,22,....
(ii) 1,-1, -3, -5,...
(iii) -2 , 2,-2, 2,-2,...
(iv) 1,1,1,2,2,2,3,3,3,...
​

Answer 1

Answer:

Only (i)

Step-by-step explanation:

in (i) the common difference between the consecutive terms is 6 and it forms an AP

The others don't have any such common difference and hence are not in AP.

The next two terms of the AP are: 28, 34.
