You can increment or decrement a number by pressing Ctrl-A or Ctrl-X when in Normal mode. The number can be at the cursor, or after the cursor.
The number can be decimal, hexadecimal or octal. You can also increment or decrement a single letter ("a...", "b...", "c..."). This is controlled with the 'nrformats' option.

101 This is an item.
In Normal mode, enter the following to record a macro into the a register. This macro yanks the current line, then pastes it below, then increments the number.
qa Y p Ctrl-A q
Now type 15@a to perform the macro 15 times. You will see:
101 This is an item. 102 This is an item. 103 This is an item. 104 This is an item. and so on
