Which of the following is the missing term, a2, of the geometric sequence in which a1=2 and a3=200

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Which of the following is true for the relation f(x)=2x^2+1
