+# Challenge 155

+# TASK #1 > Fortunate Numbers
+# Submitted by: Mohammad S Anwar
+# Write a script to produce first 8 Fortunate Numbers (unique and sorted).
+#
+# According to Wikipedia
+#
+# A Fortunate number, named after Reo Fortune, is the smallest integer m > 1
+# such that, for a given positive integer n, pn# + m is a prime number, where
+# the primorial pn# is the product of the first n prime numbers.
+#
+# Expected Output
+# 3, 5, 7, 13, 17, 19, 23, 37
