Answer:
1/4, 3 3/4, 5 1/4
Step-by-step explanation:
Solving for a[n-1], we get ...
a[n-1] = n^2 -a[n]
Then ...
a[4] = 5^2 -a[5] = 25 -14 1/4 = 10 3/4
a[3] = 4^2 -a[4] = 16 -10 3/4 = 5 1/4
a[2] = 3^2 -a[3] = 9 -5 1/4 = 3 3/4
a[1] = 2^2 -a[2] = 4 -3 3/4 = 1/4
Then the first three terms are a[1], a[2], and a[3]:
1/4, 3 3/4, 5 1/4
