I got 21, can you guess what X is?

N = number of cards

7N + X(X+1) + -2NX

@dinasaidso What are the restriction on the set of values? I.e. must X be a positive whole number? Can it be any integer? Rational? (Curious about the general rule, though of course that may be relevant to this problem.)

@keithjones absolutely. It can also be a negative number. 😜
