What is the 9th term for 1,5,25,125
Temka [501]

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 55 gives the next term. In other words, an=a1rn−1an=a1rn-1.

Geometric Sequence: r=5r=5

This is the form of a geometric sequence.

an=a1rn−1an=a1rn-1

Substitute in the values of a1=1a1=1 and r=5r=5.

an=1⋅5n−1an=1⋅5n-1

Multiply 5n−15n-1 by 11.

an=5n−1
