The best way for solving the arithmetic progressions of exercise 5.1 of class 10th math . How i solve easily this question in simple way Which of the following are APs? If they form an A.P. find the common difference d and write three more terms.(vi) 0.2, 0.22, 0.222, 0.2222 ….
Here,
a2 – a1 = 0.22-0.2 = 0.02
a3 – a2 = 0.222-0.22 = 0.002
a4 – a3 = 0.2222-0.222 = 0.0002
Since, an+1 – an or the common difference is not same every time.
Therefore, and the given series doesn’t forms a A.P.
