Population in year 2021 is, P 2021 = 2585862 + (345463 x 1) + {(1 (1+1))/2} x 87729

                                             = 3019054

                For year 2031      P 2031 = 2585862 + (345463 x 2) + {(2(2+1)/2)} x 87729

                                              = 3539975

                                             P 2041 = 2585862 + (345463 x 3) + {(3(3+1)/2)} x 87729
