Question

Find the sum to n terms of 0.2,0.22,0.222.....

Answer 1

Step-by-step explanation:

sol.=> A.P. = 0.2, 0.22, 0.222...........

=> sum of n terms = Sn = n/2[2a+(n-1)d]

=> Hence,

=> a ( 1th term ) = 0.2

=> d ( common difference) = (a2 - a1)

= 0.22- 0.2 = 0.02

= a3 - a2 = 0.222 - 0.22

= 0.002

Hence,

The Common difference is different. So this question can't be solved.

I hope it's help you!
