We use the following formula
P = PMT[((1 + r)^n - 1) / r], where P is the future value, r is interest rate, n is number of periods over which payments are made and PMT is amount of each payment, therefore
25000 = PMT[((1 + .04)^10 - 1) / .04], note that n = 5*2
25000 = PMT(12.006107125)
PMT = 25000 / (12.006107125) = 2082.273607899 approx $2082.27
each payment is $2082.27

+A+=+P%2A%28+1+%2B+r%2Fn+%29%5E%28n%2At%29+
+t+ = number of years
+n+ = number of times compounded
+r+ = rate of interest
+P+ = principle
+A+ = amount after +t+ years
-------------------------------------
given:
+25000+=+P%2A%28+1+%2B+.04%2F2+%29%5E%282%2A5%29+
+25000+=+P%2A1.02%5E10+
+25000+=+P%2A1.21899+
+P+=+20508.71+
--------------------
I found the principle, which is the original
amount of the investment
-----------------------
I'm having trouble also with the words:
"find the periodic payment" Is the period twice a year
over 5 years? That would be +10+ payments, so
+A+-+P+=+25000+-+20508.71+
+A+-+P+=+4491.29+
+4491.29+%2F+10+=+449.13+
The periodic payment ( 10 payments ) would be $449.13
DEFINITELY get another opinion on this.
The wording is vague, I think
