Let the required number be x<span>, that is </span><span>720=x⋅<span>110</span></span><span>, which means that </span><span>x=720</span>×<span>10=7200</span>.
<span>Answer: </span><span>7200</span>
I used the <span>quadratic formula to solve this problem. if you have anymore questions or cant reading my writing clearly, please message me :)

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by <span>33</span> gives the next term. In other words, <span><span><span>an</span>=<span>a1</span>⋅<span>r<span>n−1</span></span></span><span><span>an</span>=<span>a1</span>⋅<span>r<span>n-1</span></span></span></span><span>.</span>
