Which of the following forms an AP? If they form an AP, then write the next two items?
(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,……, (v) x,2x,3x,4x,…………

Text Solution

Verified by Experts

The correct Answer is:
(i) forms an AP
next forms are 22+6 = 28 and 28 + 6 = 34
(ii) is AP.
next two terms are: `-7` and `-9`
(iii) not an AP
(iv) not an ap
(v) is an AP
two terms are `4x +x=5x` and `5x+x=6x`
