Mathematics

3is the 1st term, 9 is the 2nd term, 27 is the 3rd term so then4th term: 27 x 3 = 815th term: 81 x 3 = 2436th term: 243 x 3 = 7297th term: 729 x 3 = 2,187 you can use the explicit formula

an=a1⋅rn−1, where an is the nth term, a1 is the first term, n is the number of the term, and r is the common ratio

so a7=3⋅37−1a7=3⋅36a7=3⋅729a7=2,187

both ways get you to the same answer that the 7th term in that geometric sequence is 2, 187 .
