Question

describe a pattern in the sequences of numbers. predict the next number.

1. 1,4,7,10 . . . .

2. 1,11,121,1331, . . . .

3. 7,9,13,19,27, . . . .

4. 256,16,4,2 . . . .

thanks so much!

Answer 1

1. 1,4,7,10 . . . . add 3

2. 1,11,121,1331, . . . . 11^0, 11^1, 11^2, 11^3, etc

3. 7,9,13,19,27, . . . . add 2, 4, 6, 8.... 10 next

4. 256,16,4,2 . . . . square root?

Answer 2

1. Add 3 to each previous term

2. It's 11 raised to a power   11^0 = 1

11^ 1 = 11, etc.

3. Added 2, then 4, then 6, then 8, so add 10 to 27

4. Take square root of the previous term

sqr(256) = 16

sqr ( 16) = 4

sqr ( 4) = 2

so sqr 2

Good luck to you !

Answer 3

1. 13         (+3)

2. 14,641   (x11)

3. 37         (+ the next even number)

4.  idk

Answer 4

1. 1,4,7,10, 13  -dif. of 3

2. 1,11, 121, 1331, 14641  -sq. of 11

3. 37....everytime the dif. keeps on inc. by 2

4. 1 they are sq. roots

Answer 5

1.  Add 3 -> 13

2.  Multiply by 11 -> 14641

3.  Add the consecutive even numbers -> 37

4.  Take the square root -> Square root of 2

Answer 6

1. The first one is adding three each time: 1+3=4, 4+3=7....

2. The second one is multiplying by eleven: 1*11=11, 11*11=121....

3.The third one is adding by multiples of two: 7+2=9, 9+4=13...

4. The last one is deducting by the square root: (the square root of 256 is 16 and so on
