eight, five, four, nine, one, seven, six, ten, three, two, zero
The first few natural numbers in alphabetocal order - but only for English speaking people.
For English speaking people, the numbers are in alphabetical order.
10
This sequence of numbers is in alphabetical number when written in their full form, eg; "eight".
I'm guessing your sequence is 1, 3, 6, 10, 15, ... In which case it continues: 21, 28, 36, 45, 55, 66, ... (These are the triangular numbers.)
The sequence consists of triangular numbers, which can be calculated using the formula ( T_n = \frac{n(n + 1)}{2} ). The numbers in the sequence correspond to ( T_1, T_3, T_5, T_6, T_7, T_8, T_9 ) respectively. Following this pattern, the next number is ( T_{10} = \frac{10(10 + 1)}{2} = 55 ). Therefore, the next number in the sequence is 72.
For English speaking people, the numbers are in alphabetical order.
10
This is the sequence of numbers from 1 to 10, which, when written as English words, they would be in alphabetical order.
5
Dodging numbers may be missing numbers in a sequence. For example, the underscore in the following sequence represents such a number: 2, 4, _ , 8, 10.
Up to the 10, (in English) they are in alphabetical order - Eight, Five, Four, ...
8 5 4 9 1 7 6 10 3 2 0 This sequence is special because the numbers are in alphabetical order. The Fibonacci sequence is very special and the triangular sequence.
10
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
