1)T2-T1=T3-T2 2x+6-(x-2)=4x-8-(2x+6) 2x+6-x+2=4x-8-2x-6 x+8=2x-14 x=22 2)substitute for x: 1st term:x-2=22-2=20 2nd term:2x+6=2(22)+6=44+6=50 3rd term:4x-8=4(22)-8=88-8=80 now we look for the constant difference(d): T2-T1=50-20=30 T3-T2=80-50=30 So d=30
Use the formula: A=P(1+i)^n A=? P=$5000 i=2.5/2 =1.25/100 =0.0125 n=2*18=36 now we substitute: A=5000(1+0.0125)^36 =5000(1.0125)^36 =$7819.72
