Step-by-step explanation:

11.  if you subtract the number 11 and 16 you get the number 5. if you subtract 21 and 16 you get the number 5 again.  subtract 26 and 21 you get the number 5 and subtract 36 to the number 36 you get the number 5 again.

12. Add successive powers of 2 to the number:  1+2=3; 3+4=7; 7+8=15; 15+16=31

13. 3+1=4, 4+1+1=6, 6+2+2=10, 10+4+4=18, 18+8+8=34, 34+16+16=66

14. 1 * 2 + 3 = 2 + 3 = 5. 5 * 2 + 3 = 10 + 3 = 13. 13 * 2 + 3 = 26 + 3 = 29.

29 * 2 + 3 = 58 + 3 = 61.  61 * 2 + 3 = 122 + 3 = 125

15. 6 x 2 =, 12 - 3 = 9, x 2 = 18, - 3 = 15.
