At the end of the Year n the population , Px=n+nrx+(x-1)r2n+(x-2)r3n++(x-x+2)r(x-1)x+(x-x+1)rxn=n(1+r)xAt the end of the Year 16 the population , P16= n+16rn+15r2n+14r3n++3r14n+2r15n+r16n=n(1+r)16 Thus under given condition of rate of growth, the Population P(x) at xth year will be P(x)=n(1+r)x Therefore, a population of 110,000 growing at 4% per year, in 16 years will be= 110,000(1+4/100)16= 110,000(1.04)16=206027.93702999115428132473599427≈206028
