question 6

Multiple Choice

When the odd numbers are added successively, any finite sum will be a perfect square (e.g., 1 + 3 + 5 = 9 and 9 = 3^2) . What change must be made in the following program to correctly demonstrate this fact for the first few odd numbers? Private Sab btnDisplay_Click $( \ldots )$ Handles btnDisplay.Click
Dim oddNumber As Integer
Dim sum As Integer $= 0$
For i As Integer $= 1$ To 9 Step 2 $\quad$ 'Generate first few odd numbers
oddNumber $= \mathrm { i }$
For $\mathrm { j }$ As Integer $= 1$ To oddNumber Step 2 $\quad$ 'Add odd numbers
sum $+ = j$
