does any1 know the next sequence number to 1,4,9,16__ its a pattern so if any1 knows plz tell me?

Answer 1

Squares of consecutive integers.

1*1 = 1
2*2 = 4
3*3 = 9
4*4 = 16

The next term is 25 (5*5)

Alternatively you could look at the differences between adjacent terms:

1
4 - (4-1) = 3
9 - (9-4) = 5
16 - (16-9) = 7

3, 5, 7 - consecutive odd numbers. The next difference should be 9, and 16+9 = 25.

Answer 2

there could be 2 possible answers

1^2=1
2^2=4
3^2=9
4^2=16
5^2=25

another solution
the difference between 1 4 9 16 shows a odd number pattern 3 ,5 ,7. then 9 comes next after 7.Add 9 to 16 and gives 25 as the next number in the sequence

Answer 3

25

Answer 4

Hi.I will help you. In the above case the next number must be 25. It is the addtition of the consecutive odd numbers. I will show you how. when you add 1 and 3 we get 4. Here 3 is the odd number. in the next sequence, when we add 4 and 5 we get 9. here 5 is the odd number. IN the first one, we added 3 and now 5 and later 7 and 11 and so forth. i will solve some for you. 1,4,9,16,25,36,49,64,81,100,121,144,169.

Answer 5

25

The pattern is odd numbers starting with 3 (between the 1 and 4), 5 (between the 4 and the 9), 7 (between the 9 and 16), so the next odd number is 9 (add 9 to 16 and you get the answer - 25)

Answer 6

I think the pattern is 2^n + cos((π/2)(n+1)). This yields:

n = 1: 2^1 + cos(π) = 2 - 1 = 1

n = 2: 2^2 + cos(3π/2) = 4 + 0 = 4

n = 3: 2^3 + cos(2π) = 8 + 1 = 9

n = 4: 2^4 + cos(5π/2) = 16 + 0 = 16

So, the next four numbers are 31, 64, 129, and 256

Answer 7

yes

1*1=1
2*2=4
3*3=9
4*4=16
5*5=25
6*6=36

This is a sequence of the (n*n)

Answer 8

25.

1+3
4+5
9+7
so next would be 16+9, or 25

Answer 9

25 is the answer.
It is increasing in odd number increments, 3 then 5 then 7, and so on.

Answer 10

1+3=4
4+5=9
9+7=16
16+9=25

The number that you add to each number is 2 more than the number before it [3,5,7,9]

I hope that's right.
