实现上述功能的VB程序代码如下，请在划线处填上合适的代码。

Dim a( 1 To 20) As Integer

Private Sub Command1_Click ( )

Dim key As Integer

key =   ①   

i = 1

Do While key > a ( i ) And ( i <= 1 5 )

i = i + 1

Loop

Label4.Caption = “该数插入的位置是：” + Str ( i )

If  i = 16  Then

a ( i ) = key

Else

For j = 16  To  i + 1 Step -1

    ②  

Next j

a ( i ) = key

End  If

List2. Clear

For i = 1 To 16

List2.AddItem a( i)

Next i

End Sub

Private Sub Form_Load( )

'随机生成15个200以内的正整数

Randomize

For i = 1 To 15

a ( i ) = Int(Rnd * 200) + 1

Next i

'将15个数从小到大排序

For i = 1 To 14

k = i

For j = i + 1 To 15

If a ( k ) > a ( j ) Then k = j

Next j

If  i <>k  Then

t = a(i)； a( i) = a ( k )：a ( k )

End  If

Next i

'将排好序的数输出在列表框Listl中

Listl.Clear

For i = 1 To 15

Listl.AddItem str ( a ( i ) )

Next i

End Sub

程序中①划线处应填入{#blank#}1{#/blank#}，程序中②划线处应填入{#blank#}2{#/blank#}

  Dim names(5) As String

Dim a(1 To 100) As Integer

Dim b(1 To 100) As Integer

Dim c As Integer

a(1) = 0: a(2) = 2: b(1) = 1: b(2) = 2: c = 0

For i = 2 To 6

  a(i + 1) = 2 * a(i) - a(i - 1)

  b(i + 1) = b(i) ^ 2 / b(i - 1)

c = c + a(i + 1) + b(i + 1)

Next i

Label1.Caption = Str(c)

该程序运行后，Label1中显示的内容是（  ）
