प्रश्न
Following are APs or not? If they form an A.P. find the common difference d and write three more terms:
2, 4, 8, 16 …
उत्तर
2, 4, 8, 16 …
Here,
a2 - a1 = 4 - 2 = 2
a3 - a2 = 8 - 4 = 4
a4 - a3 = 16 - 8 = 8
⇒ ak+1 - ak is not the same every time.
Therefore, The given numbers do not form an AP.
