Solve the inequality. -x/4 is less than or equal to 2.

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]

With this question, the answer with the red arrow is incorrect!

X=4 / y=100 if x=10 then what is y=?
