The initial term of the sequence is 15. The common difference is 3, so the n-th term (an) is
... an = 15 + 3(n-1)
For n=14, the 14th term of the sequence is
... a14 = 15 + 3(14 -1) = 54
The sum of terms is the average of the first and last, multiplied by the number of terms:
... sum = (15 + 54)/2·14 = 7·69 = 483
The appropriate answer choice is
... 54; 483

hello :
the quadratic function is :
<span> f(x) = a(x-1)(x+1)
but ; f(0) = -6</span>
a(0-1)(0+1) = -6
-a = -6
a=6
<span>the equation is : 6(x-1)(x+1) = 0</span>
Um it is 7.5 so..........
