GEOMETRIC SEQUENCE (Finding the nth term)

GEOMETRIC SEQUENCE

Finding the nth term of a geometric sequence.

GEOMETRIC SEQUENCE

A sequence with a common ratio.

Multiple Choice

• YES, IT IS A GEOMETRIC SEQUENCE WITH A COMMON RATIO OF 2.

• NO, IT IS NOT A GEOMETRIC SEQUENCE.

GEOMETRIC SEQUENCE

To find the nth term of the geometric sequence:

 $a_n=a_1r^{n-1}$  

GEOMETRIC SEQUENCE

To find the nth term of the geometric sequence:

 $a_n=a_1r^{n-1}$  

GEOMETRIC SEQUENCE

To find the nth term of the geometric sequence:

 $a_n=a_1r^{n-1}$
