This is a geometric sequence. Each number is multiplied by the same constant, to get the next number. If you divide any number by the previous one, you can find out what this constant is.
the next number in the sequence 1 5 25 125 is 625
25 is the next number that appears in that sequence.
Each is half of the previous number, so 6.25 will be next.
This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.
The next number will be 25 because 5 times 5 = 25
the next number in the sequence 1 5 25 125 is 625
It is 0.2
.5,.25,.125
25 is the next number that appears in that sequence.
121.
243
Each is half of the previous number, so 6.25 will be next.
It is obvious that 7 is added to get the next number from the previous one.
35
This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.
The next number in the sequence would be 25.
The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.
