What are the next letters in the pattern? (writing the alphabet and circling letters will you with this problem.)
az, dx, gv, jt,

The answer would be mr. This is because a is the 1st letter in the alphabet and z is the 26th (last). Then, d is the 4th and x is the 24th. As you can see each time the pattern increases by 3 for the first letters and decreases by 2 for the second letters. So, if you keep on going and get to jt. J is the 10th letter in the alphabet and t is the 20th. Now, you just need to add 3 to 10 and subtract 2 from 20. This leaves 13 and 18. M is the 13th letter and R is the 18th.
