In the following sequence: [x, y, z, 5, 7, 16, 28] each number is equal to the sum of the three numbers succeding it. What is x+y?	Choose the correct choice from the following options
A) 113  B) 213  C) 163  D) 213  E) 131
lets start from z, as per the question stem   z =5+7+16=

<output>28</output>
28   --&gt;&gt; z= 28   similarly, y =28+5+7   --&gt; y = 40   similarly,, x =40+28+5   --&gt; x =73   hence , x+y =73+40= 
<gadget id="calculator">73+40</gadget>
<output>113</output>
113 --&gt; x+y=113   113NSWER:113
<result>A</result>
