An arithmetically increasing annuity-immediate is an annuity that does not make level payments, but rather makes payments of P at the end of the first period, P+Q at the end of the second period, ..., P+ (k-1)Q at the end of the kth period. (1) Taking values P-1 and Q-1, let the symbol (Ia)m denote the present value of this k-0 An arithmetically increasing annuity-immediate is an annuity that does not make level payments, but rather makes payments of P at the end of the first period, P+Q at the end of the second period, ..., P+ (k-1)Q at the end of the kth period.
