Final answer:
The 8th term (a8) of the sequence defined by an = 2^n - 2 equals 254, calculated by substituting n with 8 into the formula.
Step-by-step explanation:
The student is asking for the 8th term (a8) of the sequence where each term an is defined by the formula an = 2^n - 2. To find a8, we simply substitute n with 8 into the given formula.
So, we have a8 = 2^8 - 2. Calculating the value of 2^8 first, which is 256, we then subtract 2 to get the final value for a8.
Therefore, a8 = 256 - 2 = 254
