how to say "projected numbers" in chinese (mandarin)?
First, translate to English:

"kindly provide me with the full year numbers up to october, we will use it to project for the full 12 months."

Please provide me with the figures for this year up to October, we will then use that to estimate the values for the whole year.

Given that, it can't be toooo hard to translate， though my Chinese is none too hot.

Please provide me with the figures for this year up to October,
请提供今年到十月的数据，

we will then use that to estimate the values for the whole year.
然后我们会用这些数据来估计整年的使用。  

Something along those lines.
