An annual deposits of A₁=$1,500 in a saving account is made for 6 years starting year 1. In year 9, a one-time deposit of $3,500 is made. In year 11, a one-time withdrawal of $2,500 is made. Then another series of annual deposits of A₂ started for 7 years starting from year 12, increasing by $350 every year. If a one-time withdrawal of $900 was made in year 19 and the present worth of the whole amounts of deposits and withdrawals is $-20,500, what is the value of A₂? If the whole life cycle is to be repeated forever with a life cycle of 19 years, what is the capitalized cost and the annual worth? Assume an interest rate of 6%.
