How many even integers n, such that 20<=n<=200 are of the form 3k+4, where k is any natural number?  Choose the correct choice from the following:
A) 26	B) 30	C) 34	D) 38	E) 42
The first number is 22 = 16+6(1).   We can continue adding 6 to make a list: 22, 28, 34,...   The last number is 196 = 16+6(30)   There are 30 numbers in the list.   The answer is 30.
