Question

If 1/2x +1/2(1/2x + 1/2(1/2x +1/2(1/2x + ... = y,
then x = ?


please help

Answer 1

The answer is .5 I'm positive

Answer 2

This equation can be rewritten as:
(1/2)x + (1/4)x + (1/8)x + (1/16)x + (1/32)x.... = y
That's x * (1/2 + 1/4 + 1/8 + 1/16 + 1/32....) = y
and when you sum up the stuff in the parentheses, you get 1.

Hence, the equation turns into x = y, which answers your question.

Answer 3

I'll give you a clue.

Teh above expression reduces to:
1/2x + 1/2(y) = y

Now solve for x in terms of y
