How many even integers n, such that 20<=n<=250 are of the form 3k+4, where k is any natural number?	Choose the correct choice from the following options
A) 33	B) 36	C) 39	D) 42	E) 45
The first number is 22 = 16+6(1).   We can continue adding 6 to make a list: 22, 28, 34,...   The last number is 250 = 16+6(39)   There are 39 numbers in the list.   The answer is 39.
