Question

Find the next term in the sequence: 13M, 17Q, 19S, _______

A. 21W  B. 21V  C. 23W  D. 23V

Accepted Answer

The next term is 23W, which is option C. Each term consists of a prime number paired with a letter. The numbers 13, 17, 19 are consecutive primes, so the next prime is 23. The letters M, Q, S correspond to positions 13, 17, 19 in the alphabet respectively (M=13, Q=17, S=19). So the letter of each term is simply the letter at the same alphabetical position as the number. The next number is 23 and the 23rd letter is W. Therefore the next term is 23W.
