Explanation:

for that simple request there is nothing to solve, just to follow.

follow the functional definitions given.

we know d(1) and f(1). and you need the first 5 items ?

just calculate d(2) and f(2). from there then d(3) and f(3). and so on.

d(1) = 1

d(2) = d(1)² + 1 = 1 + 1 = 2

d(3) = d(2)² + 1 = 4 + 1 = 5

d(4) = d(3)² + 1 = 25 + 1 = 26

d(5) = d(4)² + 1 = 676 + 1 = 677

f(1) = 1

f(2) = f(1) + 2×2 - 2 = 1 + 4 - 2 = 3

f(3) = f(2) + 2×3 - 2 = 3 + 6 - 2 = 7

f(4) = f(3) + 2×4 - 2 = 7 + 8 - 2 = 13

f(5) = f(4) + 2×5 - 2 = 13 + 10 - 2 = 21
