Spike has a life insurance policy with $1.5 million benefit. if this money was put into an account with a 5.2% interest rate, how much income can his beneficiaries expect in case spikes dies

The total amount of interest earned each year will be
  5.2% × $1,500,000 = $78,000


We would need to know more about the beneficiaries (their number and the way they might split the proceeds) and how they might use the balance in the account (whether interest only, or interest and principal are withdrawn) before we could answer the question asked.
