Find the sum of 30th term of the sequence 7, 7.7, 7.77, 7.777..................
Hi Madhuri!
Here is the answer to your question.
7 + 7.7 + 7.77 + 7.777 … 30 terms.
= [(7 + 0) + (7 + 0.7) + (7 + 0.77) + (7 + 0.777) + … 30 terms]
= 7 × 30 + (0 + 0.7 + 0.77 + 0.777 … 30 terms)
Hope! You got the answer.
Cheers!
