Elves get special bells on their birthdays. Help us discover how many bells
our elf will have on his birthday this year.
Berry the elf will turn 50 this year. When an elf turns 50 he receives
one silver bell. He gets another one
when he turns 52, and another when he turns 54. This pattern continues on his
even years for the
rest of his life.
When he turns 101, he gets 3 gold bells. He
gets three more gold bells when he turns 103, and so on for every odd year's
birthday.
Given these two patterns for silver and gold bells,
How many bells will Berry have to ring on his 150th
birthday?
