Answer:

14

Explanation:

Consider an analog clock. The number 3 is directly across from the number 9. The difference of those two numbers is 6, half the number of numbers on the clock face.

The difference between the numbers 4 and 11 is 7, half the number of beads on the necklace.

There are 7×2 = 14 beads on the necklace.
