Answer
This sequence is known as the Narayana’s Cows that originated from a problem with cows that was proposed by Indian mathematician Narayana in the 14th century – where there is one cow in the beginning and every cow produces one calf each year from the age of 4 years old, counting the number of calves produced every year. The next number in the sequence is 19. See more at Wikipedia.
