It's 26 because the pattern is adding 5. To find the pattern, just subtract the numbers from the ones before so 11-6 and 21- 16 which both equal 5. Then just add 5 to the last number and you'll find it to be 26.
The next number is 26. The easiest way to do these kinds of problems without using the arithmetic equation and stuff is basically find the pattern between the numbers. 6 + 5 = 11. 11 + 5 = 16. 16 + 5 = 21. 21 + ? = ? From this, we see that the number 5 is being added so the next number is 21 + 5 which is 26. I hope this helps :-)
