Question

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

Answer 1

Notice how 16^2 = 256

4^2 = 16

and

2^2 = 4

Answer 2

\[ \large a_1=256=16^2 \]
\[ \large a_2=16=\sqrt{a_1} \]

Answer 3

so whats the next number

Answer 4

You take the square root of each term to get the next term

Ex:

sqrt(256) = 16
