# Low quality posts

Some time back,I was trying to ask a question.(Find the smallest positive integer $a$ such that 1971 divides $50^n+a.23^n$ for odd n.) This is what I got: "Oops! Your question couldn't be submitted because:

* It does not meet our quality standards."


Can anyone kindly explain what this is all about?I am new to this website.Your help is appreciated.

• I don't know what the problem was, but I would have suggested you rewrite the question to look less like an order. – Mariano Suárez-Álvarez Jul 31 '11 at 4:05
