2, 7, 77, 84
-------------------------
What a strange statement. All numbers are different.
----------------
But, 2 is the only even prime number, and is the smallest prime number (1 is not considered).
7 is a prime number.
77 is the product of 2 prime numbers.
84 is an even number, and is compound (not prime), as all even numbers except 2 are.
84 has a factor of 7, as does 7 and 77. 84 is the sum of the 2 numbers preceding it, too.
