(3):  233, 234, 240<br>
In base 10, 239 plus 1 is 240, because 9 is the largest digit in base 10.  Similarly, in base 5, 234 plus 1 is 240, because 4 is the largest digit in base 5.<br>
(4):  334, 340, 341<br>
In base 10, 340 minus 1 is 339, because 0 is the smallest digit in base 10 and 9 is the largest.  Similarly, in base 5, 340-1 = 334, because 0 is the smallest digit in base 5 and 4 is the largest.<br>
