Math Problem Statement
tengo esta funcion: INF(t) - (b1_inf * 100 * ((PIBNM(t)/YPOT(t)) - 1) + b2_inf * INF(t-1) + b3_inf * (datos$lnTCR(t-1) - log(100)) * 100 + b4_inf * INF(t+1)) Aqui vemos que INF en el periodo t depende entre otras cosas de INF(t+1), es decir del siguiente periodo y el siguiente por tanto del subsiguiente, hay alguna manera de reecribir esta ecuacion como una sumatoria? y despues aplicar sumatoria geometrica, me entiendes??

INF(t) = (b1_inf * 100 * ((PIBNM(t)/YPOT(t)) - 1) + b2_inf * INF(t-1) + b3_inf * (ln(TCR(t-1)) - ln(100)) * 100) / (1 - b4_inf)
INF(t) = Σ (b4_inf^n * (b1_inf * 100 * ((PIBNM(t+n)/YPOT(t+n)) - 1) + b2_inf * INF(t-1+n) + b3_inf * (ln(TCR(t-1+n)) - ln(100)) * 100) / (1 - b4_inf)^(n+1))
