1.5                                                NUMBER PYRAMID















                    In number pyramid, the number in each space is the sum of
                    the two numbers below it.





                                                      Blue circle will be the sum

                                                      of two green circles.





                                                                                            9



                                                                                       5         4




                                                                                  3         2         2



                         2          1         1         1                    2         1         1         1







                      Start with a circle, which has two
                      filled adjoining circles below it.




                    ` Therefore, blue circle will be 2 + 1 = 3.

                    ` Similarly, if we take the green circle, the one above the blue circle, the sum

                    will be 3 + 2 = 5.

                    ` We will get the remaining numbers by following the same pattern.
