The next will be 13112221...... this problem is known as look and say each number describes previous one like
"two 1's" = 21
"one 2, one 1" = 1211
"one 1, one 2, two 1's" = 111221
"three 1's, two 2's, one 1" = 312211
A man can make perfect counterfeit bills. They look exactly like real ones, they're made of exactly the same materials, made the same way, everything. So perfect, one could pretty much call them real bills. One day he successfully makes a perfect copy of another bill. However, he gets caught when he tries to use the copy. How is this possible?
Because on his way to use the counterfeit note he steps in chewing gum, then in a puddle then when he finally gets to the store he is fuming and angry, the shop keeper then asks for the money, as he hands it over a bird fly over and poos on him. He then screams in anger! F YOU ALL, I MAKE COUNTERFEIT MONEY!!!!!! The shop keeper confused, takes a lighter to the money and rather then burning red it burns black which is the only way to be able to tell the difference.
