3 is the answer of this question

3is right answer ka answer hai

Given series 2187, 729, 243, 81, 27, 9,..... is geometric series with common ratio r= 729/2187 = 1/3and first term a = 2187

Its nth term = ar^[n-1]

Then 7th term = 2187 * (1/3)^[7-1]= 2187 * 1/(3)^6= 2187/729 = 3

Number in the place of ? will be 3.

3 is the right answer
