the formula for finding the Tn is: Tn=T1 - 4(n-1) instead of T1 we can use the number 12 since this is the
T1 for this sequence. So we will have Tn = 12 - 4(n-1) since the Tn we re trying to find out is -96 we will
have: -96 = 12 - 4(n-1) ->> -96 = 12 - 4n + 4 and solving for n we have: -96 - 12 - 4 = -4n ->>
-112 = - 4n and. n = -112 / - 4 = 28 so Tn=T28
