We have sequence equation
.
In this case n is a natural number (1, 2, 3, ...).
So start inserting and computing value of
given that you know the value of n and a.
(first term)

Hope this helps.
Answer:

Explanation:
Since, there are two possible outcomes for every toss (head or tail), the sample space for<em> a coin tossed 8 times</em> is 2×2×2×2×2×2×2×2 = 2⁸ = 256.
<em>Landing on heads all 8 times</em> is just one of the possible outcomes: HHHHHHHH ⇒ 1.
Hence, the <em>probability </em>is calculated from its own definition:
Probability = number of favorable outcomes / number of possible outcomes
