firstly u multiply with .5 and subtract 1....after that multiply by 1...
after that 2 and than 3..so on...
but it's not the exact logic...becoz...if u fst multiply by .5 then next will be 1....(.5+.5=1)

after  that (1+1=2) and then the next term will be (2+2=4)...i think the series may continue like this....!!

.5,1,2,3,4....hw it is possible....plzz explain
