User: What is the 8th term in the sequence?

Weegy: 1) 8, 4, 2, 1, ... Here, common ratio: r = 1/2, first term: a = 8 Hence, the eighth term = a*r^(n-1) = 8*(1/2)^7 = 8/2^7 = 1/2^4 = 1/16 2) 3, 15, 75, 375, 1875, ... Here, common ratio = (n + 1th term)/(nth term) n=1, [ => common ratio = 15/3 = 5 3) 25, 5, 1, 0.2, ... Common ratio: r = 5/25 = 1/5 First term: a = 25 => 10th term = a*r^(10-1) = 25*(1/5)^(9) = 5^2/5^9 = 1/5^7 = 0.0000128 4) 3, 3/2, 3/4, 3/8, 3/16 Common ratio = (3/2 )/ 3 = 1/2 5) 3, 18, 108, 648, 3888, ... Common ratio = 18/3 = 6 Hence, 10th term please leave a good rating... much appreciated ]

-1119744 is the 8th term in the sequence :4,-24,144,-864 .
common ratio = -864/144 = -6
8th term = 4*(-6)^(8 - 1) = 4*(-6)^7 = -1119744
