Write the sum using summation notation, assuming the suggested pattern continues.

-1 + 2 + 5 + 8 + + 44

a) summation of negative three times n from n equals zero to fifteen
b) summation of the quantity negative one plus three n from n equals zero to fifteen
c)summation of negative three times n from n equals zero to infinity
d) summation of the quantity negative one plus three n from n equals zero to infinity

The answer is C. Summation of negative three times n from n equals zero to infinity

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
