Seems like each number is obtained by adding 3 to the previous number. Hence the next three numbers are 13, 16, 19

∙ 9y agoLooks like an arithmetic progression of (-3). 10-3=7; 7-3=4; 4-3=1; 1-3=-2
They are: 0, -5, -10
10 the sequence is 3 numbers miss one, three numbers miss one, etc
To work out Pascal's Triangle, you start with two ones at the top. From there on, you add the two numbers above to get the next number. The numbers on the outside will always be 1. ....1.....1 ...1...2...1 ..1..3...3..1 .1.4...6...4.1 1 5 10 10 5 1
7 because 1 2 3 4 5 6 7 8 9 10 10-1 9-2 8-3 7-4 6-5
6. 5-3-1 10-8-6
15, 21 (the triangular numbers)

The variance of the numbers 1 7 10 and 3 is: 16.25
The pattern is +5, -7... the answer is 6
They are: 0, -5, -10
10:4

The prime numbers from 1 to 10 are: 2, 3, 5, 7
7 because 1 2 3 4 5 6 7 8 9 10 10-1 9-2 8-3 7-4 6-5
1+10 - 2 (2 is one less than 3, the next answer in the sequence) = 9. 10 + 3 - 8 (8 is one less than 9) = 5 3 + 9 - 4 = 8 etc...; so the next two numbers in the sequence will be 11 and 5.
