Is the following sequences are A.P.? If is A.P. find the common difference.
0.3, 0.33, 0.333,...
उत्तर
0.3, 0.33, 0.333,...
Here,
The first term, a1 = 0.3
Second term, a2 = 0.33
Third term, a3 = 0.333
Now,
Common difference = a2 - a1 = 0.33 - 0.3 = 0.03
Also, a3 - a2 = 0.333 - 0.33 = 0.003
Since the common difference is not the same.
Hence, the terms are not in Arithmetic progression.
