Answer:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 4
gives the next term. In other words,
an=a1.rn-1.
Geometric Sequence:
R=4
This is the form of a geometric sequence.
an=a1rn-1
Substitute in the values of
a1=11 and
r=4.an=(11)(.)4)n-1
Remove parentheses.
an=11.4n-1
