1.找规律，第1幅图中有2个，第2幅图中有5个，第3幅图中有8个，第4幅图中有11个，第n幅图中有（ ）个？2.解方程。x/8分之5=12分之13.找规律，第1幅图中有1个，第2幅图中有5个，第3幅图中有9个，第4幅图中有13个，第n幅图中有（ ）个？本人读五年级，不要讲得太深奥！

Answer 1

1.后一个数减去前一个数为3 所以第n附图为 3*n-1
2. 题看不懂 要是左边分子为5*x 那x=13*8/12*5=26/15
3.后一个减去前一个数为4 第n附图为4*n-3

Answer 2

第一题：2=1×3-1;5=2×3-1;8=3×3-1;11=4×3-1;
综上所述：第n幅图中有：（n×3-1）个:
第二题： 5/x÷5=13/12
（ 交叉相乘：）12×5=13×（x÷8）
60=13x÷104
104×60=13x
6240=13x
x=480
第三题：1=1×4-3;5=2×4-3;9=3×4-3;13=4×4
综上所述：第n幅图中有：（n×4-3）个

Answer 3

1. 3n-1

BACnet with the Internet connectivity

Chinese Abstract: A comparative analysis of the current two kinds of BACnet and Intemet interconnect technology that B / IPPAD and BACnet / IP, and pointed out that these two kinds of technology problems. BACnet Gateway is proposed based on the interconnection model,christian louboutin pas cher, this gateway work in the BACnet network layer,abercrombie paris, you need to configure a separate IP address and a BACnet network numbers, but also must maintain a peer gateway IP address and the BACnet network numbers local database. The model is completed by the BACnet Gateway to the semantics of conversion between different protocols,abercrombie paris, broadcasting and management functions for the BACnet network and the Intemet provides a unified between the network interface and enhance the building control network and Internet integration capabilities, and greatly simplifies the BACnet network interconnection with the Internet course. In the model system to study the structure and work processes on the basis of the model implementation.
