It is 10 (make proportions and solve for x)
<span>To do this, let f(1) = 5 and f(n) = f(n-1) for n greater than 1. This is recursive rule and each term is the same because it eventually becomes f(1), which is 5.</span>
The solution of given inequality is: 
<em><u>Solution:</u></em>
<em><u>Given inequality is:</u></em>

We have to find the value of "x"
<em><u>Let us solve the given inequality</u></em>
Divide both sides of inequality by 7

<em><u>Simplify the above expression</u></em>




Thus the value of x is
