Answer
1, 2, 3, 4, 5
Explanation
Given the following data
a(0) = 0
a(i + 1) = a(i) + 1
Find a(0) to a(5)
Step 1: find a(i) when i = 0
a(0 + 1) = a(0) + 1
Where a(0) = 0
a(1) = 0 + 1
a(1) = 1
Find a(2) when i = 1
a(i + 1) = a(1) + 1
a(1) = 1
a(1 + 1) = 1 + 1
a(2) = 2
find a(3) when i = 2
a(2 + 1) = a(2) + 1
a(3) = 2 + 1
a(3) = 3
Find a(4) when i = 3
a(3 + 1) = a(3) + 1
a(4) = 3 + 1
a(4) = 4
Find a(5) when i= 4
a(4+1) = a(4) + 1
a(5) = 4 + 1
a(5) = 5
Therefore,
a(1) = 1
a(2) = 2
a(3) = 4
a(4) = 4
a(5) = 5
The answer is 1, 2, 3, 4, 5
