Maths Teaser: Password

This maths teaser is slightly different - getting the correct answer gains you the password to a hidden area of PrestonLodge.net, but you’ll have to use your skills as a mathematician to get it. The password is made up of 5 digits; here are your clues:

The fourth number is 1 more than the second number.

The second number plus the third number equals nine.

The 5th number plus the third number equals 8.

The 1st number is one less than four times the second number.

The sum of all five numbers is 20.

But the first problem is, where is the hidden area of this site?…
