At first glance, we see powers of 2 in the denominator of every term except the first one.
But if we remember 2^0 = 1, we get our breakthrough.
1/2^0 = 1/1 = 1
Therefore, we stagger the powers of 2 by 1 less than the term we are on:
a(n) = 1/2^(n - 1)
But if we remember 2^0 = 1, we get our breakthrough.
1/2^0 = 1/1 = 1
Therefore, we stagger the powers of 2 by 1 less than the term we are on:
