The next three numbers in the sequence are 23, 25, and 27.

100 200 20

25 36 49 64 81 100 121 144

The numbers are the set of square numbers. Next in the list is 52 = 25.

The first thing to notice is that all the numbers in the sequence are square numbers. 25=5x5 36=6x6 49=7x7 64=8x8 81=9x9 So the next three numbers to be squared are 10, 11 and 12. 10x10=100 11x11=121 12x12=144 Thus, the next three numbers in the sequence are 100, 121, 144 The equation for the sequence is (n+4)2

45 then 58

23, 25, 27

You can use sequences ending in every number from 3 to 25 so 23 times.

25 is the next number that appears in that sequence.

23 21 (33 or 19)

This sequence is the squaring of the numbers 1, 3, 5, and 7. The next number is 9^2 = 81.

1/5 , 1/25 , 1/125

75. The sequence is:- multiply by three, divide by two, add one.

7^2 = 49 and 8^2 = 81

the mean of four numbers is 25 and three of the numbers are 17 23 and 25 what is the fourth number?

23 25 28

25 100 80

81

One possibility: 25, 50 and 75 are three numbers with a GCF of 25.

The next number in the sequence is 27. To get the next number, double the number and add one. Except for the second number, all the numbers in the sequence follow this rule.

There appears to be no discernible pattern for these numbers, other than them increasing in arbitrary multiples of 6.

The sequence continues: 49, 64, 81, 100, 121, 144, 169, 196, 225, .... The given sequence is the squares of the numbers 2, 3, 4, 5, 6 so the next numbers in the sequence are the squares of 7, 8, 9, 10, 11, ...

Final sequence:- 1,4,9,16,25,36,49,64,81,100,121,144,169,196… This is a pattern of square numbers. 1^2=1, 2^2=2, 3^2=9, 4^2=16, and 5^2=25. The next number would be 36 because 6^2 equals 36.

The next numbers in the series are 32 and 57. This is reached by adding successive square numbers 1, 4, 9, 16, 25 and so on.
