Take a look at the following sequence of letters. Can you figure out which letter replaces the question mark?
E J ? T
How about which number replaces the question mark in this sequence of numbers?
5, 7, ? 17, 25
And one more with letters again?
R N ? F
Please leave your answers in the comments. I’d love to see them!
