first you add 1 by 5 and get 6 then .add 6 by 2 and get 8 .and add 8 by 3 and get 11.add 11 by 4 get 15.add 15 by 5 get 20 its simple just keep adding each number by 1,2,3,4,5 and if the pattern continues keep going

Each successive number is the sum of the previous number times 2, plus 1.

is this question number 10? 4n - 1 creates the pattern 3, 7, 11, 15, 19, etc.

One possible rule is: Un = (243n5 - 4210n4 + 27225n3 - 60830n2 + 106452n - 45960)/120 for n = 1, 2, 3, etc

21-28-36-45-55-66-74-87-101

The rule for the nth term is t(0) = 23 t(n) = mod[t(n-1) + 2n-1, 26] for n = 1, 2, 3, ...

multiplication pattern

One possible rule is: Un = (219n5 - 3755n4 + 24075n3 - 70645n2 + 92166n - 36960)/120 for n = 1, 2, 3, etc

The rule is 5, 10, 15 and so the next number will be 20+31 = 51

Start at 1. Multiply by 3. Subtract 1. Multiply by 3. Subtract 1. Repeat this pattern.

The rule is t(n) = 5 + 2*n, where n = 1, 2, 3, ...

Each successive number is the sum of the previous number times 2, plus 1.

255 ÷ 1 = 255 255 ÷ 3 = 85 255 ÷ 5 = 51 255 ÷ 15 = 17 255 ÷ 17 = 15 255 ÷ 51 = 5 255 ÷ 85 = 3 255 ÷ 255 = 1

is this question number 10? 4n - 1 creates the pattern 3, 7, 11, 15, 19, etc.

There are many possible answers. One possible rule is: Un = (3n4 - 18n3 + 69n2 - 54n + 120)/8 for n 1, 2, 3, ...

One possible rule is: Un = (243n5 - 4210n4 + 27225n3 - 60830n2 + 106452n - 45960)/120 for n = 1, 2, 3, etc
