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

1).18,29,42,53,-,77...?

29-18=11,

42-29=13,

53-42=11, next will be 13 dif so add 13 to 53.i.e.66

66-53=13,

77-66=11.

2). 36,18,6,3,1,?.

36/2=18,

18/3=6,

6/2=3,

3/3=1

1/2=0.5.alternate division by 2 and 3.

3).1,244,163,190,181,?

244-163=81,

190-163=27,

190-181=9, next will be 3 so add 3 to 181

184-181=3.

4).256,-,190,167,148,131.

Diff is prime numbers.

148-131=17,

167-148=19,

190-167=23,

Next will be 29,so add 29 to 190. 190+29=219.
