Question 21 • Algebra I

What is the pattern in the values as the exponents increase? Powers of 2 Value 2 to the negative 5 power 1 over 32 2 to the negative 4 power 1 over 16 2 to the negative 3 power 1 eighth 2 to the negative 2 power 1 fourth 2 inverse 1 half 2 to the 0 power 1

Answer
A
add 1 over 16 to the previous value
B
divide the previous value by 2
C
multiply the previous value by 2
D
subtract 1 over 16 from the previous value

Explanation

As the exponent increases by 1, each value doubles: 1/32 becomes 1/16, then 1/8, 1/4, 1/2, and 1. Therefore, the pattern is to multiply the previous value by 2, choice C.
