Question

Predict the next number

1. 7,9,13,19,27

2. 256,16,4,2

Answer 1

1. 37

7 + 2 = 9

9 + 4 = 13

13 + 6 = 19

19 + 8 = 27

27 + 10 = 37

2. square root of 2

square root of 256 = 16

square root of 16 = 4

square root of 4 = 2

square root of 2 = 1.4142

Answer 2

1. Adding 2,4,6,8 between each term, so next one is 27+10=37

2. Taking square root each time, so next is sqrt(2)

Answer 3

For number 1 its a increase of 2 then 4 then 6 the 8 so the next number is 37.

for number 2 its the square root of the previous number so the next number is the square root of 2

Answer 4

For sequence 1, you appear to be adding increasing even numbers.  For example 9 = 7+2, 13 = 9+4, 19 = 13+6, 27 = 19+8.  The next number is most likely 37 = 27 + 10.

For sequence 2, we are taking successive square roots: 16 = sqrt(256), 4 = sqrt(16), 2 = sqrt(4).  The next number in the sequence by this method should be sqrt(2).

Answer 5

1. 37 (it goes up by climbing even numbers. 7+two=9, 9+four=13, 13+six=19)

2. 1.41 (its the square root of the number. square root of 256=16 SR  of 16=4 and so on...)

Answer 6

1 plus 2, then plus 4, then plus 6, then plus 8, see the pattern?

so next one is 37 (27 plus 10)

#2 just keep taking the square root (16 is square root of 256, 4 is square root of 16, 2 is square root of 4)

so the next one is square root of 2.
