The sequence indicates that one number is added to the previous number to find the value of the next number. Example 1 (+0) - 1 (+1) - 2 (+1) - 3 (+2) - 5 (+3) - 8 (+5) - 13. The next number in the sequence would be 21 (13 + 8).
You are given the first number. The next number is its square. The next number is 2 more than the preceding number. The following number is 1 less than the preceding number. The pattern continues with the square of that number. 1 1 = the square of 1 3 = 1 + 2 2 = 3 - 1 4 = the square of 2 6 = 4 + 2 5 = 6 - 1 25 = the square of 5 The next number would be 27 since it is 25 + 2. The following number would be 26 since it is 27 - 1.
1 1 2 3 5 8 and 13 are a sequence so the answer would be:
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
5 + 8 = 13
Finally, the answer is:
8 + 13 = 21
Continuing endlessly
13 + 21 = etc.
It's called Fibonacci's number 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ..........
(Cf. in 'Related links' just below this answer)
Unfortunately, "logical" does not yield a single answer. One possibility is -11.
The logic behind that is to fit the cubic equation:
t(n) = (-8n3 + 69n2 - 184n + 162)/3 for n = 1, 2, 3, ...
10 the answer is 8 as according to the previous sequence it is difference of 2 than 1 than2 and again 1 now the difference of two will make it 8
343
27
125 (the sequence is successive numbers cubed)
729
13 ...23 ...33 ...43 ...53=125■
343.
125 the number cuts in half everytime
the next number in the sequence 1 5 25 125 is 625
168 is the next number. This is assuming that the sequence is the express stops with numerical values for A-train in Manhattan.
327
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.
Your sequence seems to be a cubed sequence, but you are missing 64 between 27 and 125.13 = 123 = 833 = 2743 = 6453 = 12563 = 216So, next would be 73, which equals 343.
The next one is 125.
It is 0.2
