Answer» (i) `4,10,16,22...` Here, difference between each term is `6`. So, it is an `AP`. Its next two terms will be `28,36`. (ii)`1,-1,-3,-5...` Here, difference between each term is `-2`. So, it is an `AP`. Its next two terms will be `-7,-9`. (iii)`-2,2,-2,2...` Here, difference between each term is not consistent. Sometimes, it is `4` and sometimes it is `-4`. So, it is not an `AP`. (iv)`1,1,1,2,2,2,3,3,3...` Here, difference between each term is not consistent. Sometimes, it is `0` and sometimes it is `1`. So, it is not an `AP`. |
