                                                                                                                                            Number Pyramid

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

                                                                                                                                               Start with a circle, which has two filled adjoining circles below it.
                                                                                                                                              Here, blue circle is the sum of two green circles.

                                                                                                                                               Therefore, blue circle is 2 + 1 = 3.
                                                                                                                                                We can get the remaining numbers by following the same pattern.
