Answer (2)

a n ​ = a 1 ​ . r n − 1 a 10 ​ = ( 0.2 ) . 5 9 a 10 ​ = ( 0.2 ) .1 , 953 , 125 = 390 , 625

The 10th term of the geometric sequence is calculated using the formula a n ​ = a 1 ​ r n − 1 , where the first term is 0.2 and the common ratio is 5 . By substituting these values, we find that the 10th term is 390625 .
