Just a little bit of prime number trivia to reinforce:  2 and 5 are both prime numbers and very similar.  2 is the only even prime number.  Although 5 is an odd number, it's almost like an even number in the sense that it occurs in the middle of a decad.  Obviously there are no further prime numbers that end in 2 because 2 is an even number (there can be no other even prime numbers).  Likewise there are no further prime numbers that end in 5.  Every odd number ending in a 5 beyond 5 is divisible by 5.
