Negative four
if you add a number and its (additive) inverse, you will always get 0. 1 + (-1) = 0 2 + (-2) = 0 3 + (-3) = 0 4 + (-4) = 0 5 + (-5) = 0 and so on....
Add a ".0" to the end of the number. Ie. 4 -> 4.0 123 -> 123.0
8.0 x 104 Put the period after the first number which isn't a 0, then add x 10 with the number of 0's necessary to put the number back to 80,000, which is 4.
-1,-2,+2,-4,+4,-5,+5, +0. the sequence is subtract twice, add once, subtract again, add, then subtract, then add twice.
Negative four
the next number in the sequence is 25............starting at the beginning, you add the odd numbers to the existing number to get the answer. Add "1" to 0, get 1; add "3" to 1, get 4; add "5" to 4, get 9; add "7" to 9 to get 16........and add "9" to 16 to get 25.........

6 digit value 128,64,32,16,8,4,2,1 0 0 0 0 0 1 1 0 add the number above the 1s 4+2=6
to every triangle add one number extra than you add from before e.g. (+0)0, (+1)1, (+2)3, (+3)6, (+4)10 etc
Not possible ! The digits add as follows... 1+0+1 = 2 1+0+2 = 3 1+0+3 = 4 1+0+4 = 5 1+0+5 = 6 1+0+6 = 7 1+0+7 = 8
0 The next logical number in this series would be 0. The number after that would be 9 followed by another 0. The pattern can be understood as pairs that add up to nine. 3 and 6 add up to 9. 2 and 7 add up to 9. 1 and 8 add up to 9. Each large number is 'cushioned' by two of its smaller complimentary counterpart. Similarly if we were to ask which number precedes this pattern it would be 5 since the 4 and 5 add up to 9.

-4
Pattern: Start with 0, add 2, then add 4, then add 6, then add 8,... The last term should have 16 added to it, so the next term will be 72.
