The world population in 1992 is 5.42 billion. If its population doubled every

41 years, what would its population be in 41 years?

41 years, what would its population be in 82 years?

82 years, what would its population be in 164 years?

  • math -

    well, I'd say 4.42*2 billion
    then, in 82 = 41+41, 4.42*4
    then, in 164 = 82+82, 4.42*4
