18 - 3 = 15 years of investment.
every 3 months is compounded quarteerly.
15 years * 4 quarters per year = 60 quarter.
2 and 7/12% per quarter = 2.58333333...% per quarter.
this is a one time investment at the beginning of the invewtment period.
the formula to use is f = p * (1 + r) ^ n
f is the future value
p is the present value
(1 + r) is the growth factor per quarter
n is the number of quarters.
the formula becomes f = 20,000 * (1+.0258333333...) ^ 60 = 92,392.86.
that's  how much will be in the account at the end of the investment period.
