2.- a1= -34/9 d= 2/3 9 terminos
OPERACION:


a1+d     =  -34/9 + 2/3 = -102+18/27= -84/27


• -84/27 + 2/3 = -252+54/81 = -198/81


• -198/81 + 2/3 = -594+162/243 = -432/243


• -432/243+ 2/3 = -1296+486/729 = -810/729


• -810/729 + 2/3 = -2430+1458/2187 = -972/2187


• -974/2187+2/3 = -2916+4374/6561 = -1458/6561
