hello :
note : the n th term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d and A1 the first term
in this exercice : d = -3-(-7) =-7-(-11) = 4 A1 = -11
when : n =93 you have the 93rd term A93
so : A93 = -11 +(93-1)(4)
A93 = 357
Divide 455 by 65 and get 7 multiply it by 4 and get 28. 28 dvds will be given away.
