Describe a pattern in the sequence of numbers. Predict the next number.
256,16,4,2,...

It appears to me the next number is the square root of the preceeding number. What is the square root of 2?

Is it 4?

No. The square of 2 is 4. The square root of 2 MUST be smaller than 2. Pick up your calculator and take the square root of 2.

I got 1.414213561. Would it be 1.4?

It depends upon how many places you want to carry it. Since 256 has three places, I would carry the square root of 2 to 3 places and write 1.41.
