Answer 2

Answer:

$x=520,y=738$

Step-by-step explanation:

Given: A series $2,10,30,68,130,222,350,x,y$.

To find: Value of $x,y$.

Notice that in the given series the pattern is:

$1^{3}+1=2\\2^{3}+2=10\\3^{3}+3=30\\ 4^{3}+4=68\\ 5^{3}+5=130\\ 6^{3}+6=222\\ 7^{3}+7=350\\ 8^{3}+8=520\\ 9^{3}+9=738$

Hence value of $x=520,y=738$.
