The rule is 5 10 15 20 25 30 .... etc and accordingly the next number in the sequence will be 106

The pattern here seems to be to add ten, then subtract five.16 + 10 = 2626 - 5 = 2121 + 10 = 31So: 31 - 5 = 26

-31. The rule is t(n) = -2n3 + 12n2 -19n + 14 where n = 1, 2, 3, ...

16 to 26 (+10) 26 to 21 (-5) 21 to 31 (+10) 31 (-5) = 26 26

The gaps are 5, 10, 15, 20, ..... The rule becomes add 5(n-1) to the previous number So that the second number is found by adding 5 times (2-1) to 1 = 5+1 = 6 and the third number is found by adding 5 times (3-1) to 6 = 10+6 = 16 and the fourth number is found by adding 5 times (4-1) to 16 = 15+15 = 31 and so on....

31 over 16 as a mixed number = 115/16

Well the pattern in add 10 then minus 5. So 31 minus 5 is 46.

31 - 16 = 15

31/0.16 = 193.75 Therefore, 31 is 16 percent of 193.75.

The pattern is +5, +6, +7, so the next number will be 23 + 8 or 31.

16 fifths as a mixed number = 31/5

It is: 4 2 4 2 4 ... etc So the next number will be 29 followes by 24 by means of subtraction

It is only divisible by itself and one so therefore 31 is a prime number
