what is next series 1,5,12,24,43,?

• ANSWER=71
  
  ..differences between the no.s are 4,7,12,19
  .The logic behind these no.s is we should add consecutive odd no.s to get the next no..i.e for series 4 ,7 , 12 ,19 we get 4+3=7(which is second term of series)
  we get 7+5=12(third term in series)
  12+7=19(...)
  so next term in series =19+9=28 .this is the difference b/w 5 th and 6 th number in the orginal question series .so answer is 43+28=71
