The rule is 5 10 15 20 25 30 .... etc and accordingly the next number in the sequence will be 106
a
The rule is 5, 10, 15 and so the next number will be 20+31 = 51
31
it's 0..
192
a
31
The rule is 5, 10, 15 and so the next number will be 20+31 = 51
It is 26 followed by 31
There are no letters in that sequence. The progression of numbers can beextended according to the rule shown by appending '26' as the fifth term.
26 As far as I can tell the sequence is +10,-5,+10,-5.
The next number in the sequence 5-7-13-31 is 69.
(1) Take the difference of the two previous numbers in sequence (2) Add 4 to this difference. (3) Take the number from step #2 and add it to the previous number in the sequence. For example, to find the next number in the sequence: (1) 121 - 90 = 31 (2) 31 + 4 = 35 (3) 121 + 35 = 156
106
The pattern is +5, +6, +7, so the next number will be 23 + 8 or 31.
I think the next few numbers in the sequence are 26, 36, 31, 41, 36 because I notice a pattern; add ten, subtract five, add ten
86. Use the rule t(n) = (10n3 - 75n2 + 175n - 78)/2 for n = 1, 2, 3, ...
