36%2F7%2B24%2F7%2B16%2F7%2B32%2F21%2B%22%22%2A%22%22%2A%22%22%2A%22%22 
See if this is a geometric series:







They are all the same so it is a geometric series 
with the common ratio r = 2/3

S%5Binfinity%5D%22%22=%22%22a%5B1%5D%2F%281-r%29%22%22=%22%22%2836%2F7%29%2F%281-2%2F3%29%2836%2F7%29%2F%281%2F3%29%22%22=%22%22
