I need to find the 9th term of this sequence

Mathematics

Sindrei [870]2 years ago
8 0

9514 1404 393

Answer:

  26,244

Step-by-step explanation:

The sequence is geometric with a common ratio of -3. The general term is ...

  an = (a1)r^(n-1)

The first term is 4, so we have ...

  an = 4·(-3)^(n-1)

For n=9, we find the 9th term to be ...

  a9 = 4·(-3)^(9-1) = 4·3^8

  a9 = 26,244

_____

<em>Additional comment</em>

When -3 is raised to an even power, the sign of the product is positive, the same as 3 raised to that power.
