प्रश्न
Which of the following form an AP? Justify your answer.
2, 22, 23, 24,...
उत्तर
We have a1 = 2 , a2 = 22, a3 = 23 and a4 = 24
a2 – a1 = 22 – 2
= 4 – 2
= 2
a3 – a2 = 23 – 22
= 8 – 4
= 4
Clearly, the difference of successive terms is not same
Therefore given list of numbers does not form an AP.
