Question
how do i find the pattern for:
-4,8,-12,16
if the last number is negative, multiply by -1 then add 4
if the last number is positive, add 4, then multiply by -1
or how about
term<sub>n+1</sub> = (abs(term<sub>n</sub>))*(-1)^n, where term<sub>1</sub> = -4, n>0
oops that last line should have said:
term<sub>n+1</sub> = (abs(term<sub>n</sub>)+4)*(-1)^n, where term<sub>1</sub> = -4, n>0
