Enter the explicit rule for the geometric sequence.15, 3, 3/5, 3/25. . . .an=_____________
Accepted Solution
A:
the explicit formula for geometric sequence is: an=ar^(n-1) From our sequence: 15, 3, 3/5, 3/25. . . . first term is: a=15 common ratio, r=3/15=1/5 thus the explicit formula for our sequence is: an=15(1/5)^(n-1)
