Answer:

Year of death was 1727 at age 84

Step-by-step explanation:

Let my current age was X

Newton was appointed chair when I was (1/ 3)X - 2 old

Eighteen years later

18 + (1/3) X - 2 = (1/2) X + 2

16 -2 = (1/2 -1/3)X

14 = (1/6) X

84= X

The age of death is 1699 + 1/3 X

1699 + (1/3) * 84

1699 + 28

1727
