-0.5

-1/2

Step-by-step explanation:

Step by step

Step 1 of 2: Convert decimal to fraction.

Convert decimal to fraction

negative 0.5−0.5 = negative 5 over 10−  5 /10

Step 2 of 2: Simplify.

Simplify

negative 5 over 10−  5/ 10

= negative 1 over 2−  1 /2

negative 1 over 2 −  1 2

=negative 0.5−0.5

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
