**drwls**, Sunday, July 4, 2010 at 1:04pmLife expectancy (E) increased (73.5-70.9)/4 = 0.65 years per year during that period.

If t=0 represents 1990, then

E = 70.9 + 0.65 t

Use that formula for E(19), and then do the rounding.

It is very unlikely that life expectancy will increase at that linear rate for 19 years, but that is what they are asking you to assume.
