What is the 7th term of the geometric sequence where a1 = 1,024 and a4 = –16?

Answer 1

for a GP,,an = ar^(n-1)
put n =4 ..you know a already..thus calculate r
then put n=7,,and calculate a7

Answer 2

what's r?

Answer 3

the common ratio..
for e.g. in this GP 3,6,12,24... r=2

Answer 4

whats the answer?

Answer 5
