    [SOLVED] Life expectancy

    Given e93 = 2.4, e94 = 2.3, and e95 = 2.2. Out of 4,400 alive at age 93, how many will survive to age 95?


    The answer is given as 2,300. I know the life expectancy at age x: lx = Px(1 + ex+1) , with Px = (lx + 1) / lx, which is the survival rate at age x. But I'm getting confused ... is it saying P93 = 4400 and asking for P95 ?

    Thanks!

    [sorry I tried making the subcripts but I can't get it to stay, but the 93, 94, and 95 are subscripts as well as the x's and x+1's]
