Again, a spreadsheet or suitable calculator makes this short work.

The sum is 184.

_____
The terms being summed are ...
  2·3² +3 = 2·9 +3 = 18 +3 = 21
  2·4² +3 = 35
  2·5² +3 = 53
  2·6² +3 = 75
Their total is
  21 +35 +53 +75 = 184

Answer:

  b2 = 2A/h -b1

Step-by-step explanation:

The usual formula for the area of a trapezoid is ...

  A=\dfrac{1}{2}(b_1+b_2)h

We can solve this for b2:

  \dfrac{2A}{h}=b_1+b_2 \qquad\text{multiply by $\dfrac{2}{h}$}\\\\ \dfrac{2A}{h}-b_1=b_2 \qquad\text{subtract $b_1$}\\\\ \boxed{b_2=\dfrac{2A}{h}-b_1}
