The area of the rectangle is of the form 6x² - 9x - 15
Factoring the given expression,

Length of the rectangle is 2x - 5
Thus,

<h3>The breadth of the rectangle is 3x + 3 </h3>
Tn=n²+3
from 4 to 7....the difference is 3, then from 7 to 12 the difference is 5 and from 12 to 19 the difference is 7
therefore we constantly add 2 to the difference
