+B%5B1%5D+=+1+
+B%5Bn%5D+=+%28+B%5Bn-1%5D+%29%5E2+%2B+5+
-------------------------
+B%5B2%5D+=+%28+B%5B1%5D+%29%5E2+%2B+5+
+B%5B2%5D+=+1%5E2+%2B+5+
+B%5B2%5D+=+6+
--------------
+B%5B3%5D+=+%28+B%5B2%5D+%29%5E2+%2B+5+
+B%5B3%5D+=+6%5E2+%2B+5+
+B%5B3%5D+=+41+
----------------
+B%5B4%5D+=+%28+B%5B3%5D+%29%5E2+%2B+5+
+B%5B4%5D+=+41%5E2+%2B+5+
+B%5B4%5D+=+1681+%2B+5+
+B%5B4%5D+=+1686+
-----------------
Looks OK to me
