JUST number 7 and 8
Thanks everyone
ak = 3 • 6k – 1
ak = 6 • 3k
ak = 3 • 6k
The explicit formula for the sequence that correspond to this geometric series: 6 + 18 + 54 + 162 + 486 is
Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The given geometric series is 6 + 18 + 54 + 162 + 486
a is the first term which is 6
Let us find the common ratio r which is 18/6 =3
The general form of geometric sequence is a
Let us plug in the values of a and r in the above formula
Hence, the explicit formula for the sequence that correspond to this geometric series: 6 + 18 + 54 + 162 + 486 is
