Hello :
<span>A partial sum of an arithmetic sequence is :
Sn = n/2(U1+Un)
U1 = 5 d : the common difference is : 13-9 = 9-5 =4
calculate : n
Un = U1 + (n-1)d
441 = 5 +(n-1)(4)
441 = 5 + 4n - 4
4n = 440
n =110
so :
</span><span> 5 + 9 + 13 + . . . + 441 = 110/2(5+441) = 24530</span>
The answer is the surface area will be 440 square inches less.
