1/4, -1/8, and 1/16

Step-by-step explanation:

Geometric sequence:   -2, 1, -1/2,

Geometric sequence means there is a common ratio.

so from -2 , the next term is  -2*r , and the next term is -2*r*r

-2r = 1, means  r = -1/2

then next after -1/2,  is  1/4,

and then...   -1/8, and then  1/16

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c
