Answer 2

It seems like you've provided a series of numbers and an equation, but the equation you've given is a bit unclear due to formatting. Let's break down what you've provided:

1. Series of Numbers: 13, 7, 9
2. Equation: (2,64 + 2 7 9)

However, the equation format is not standard. It appears that you're using commas and spaces in an unconventional way. If you could provide the equation using standard mathematical notation, I'd be happy to help you solve it or provide information about it.
