<PRE><B>Question 1168267</B>
&lt;br&gt;
(Corrected response; I read EVEN integers originally....)&lt;br&gt;
(1) Using formal algebra (slow; but you should now how to do it....)&lt;br&gt;
x = 1st number
x+1 = 2nd
x+2 = 3rd
x+3 = 4th&lt;br&gt;
The sum of the 1st and 3rd is 60:&lt;br&gt;
{{{x+(x+2) = 60}}}&lt;br&gt;
Solve for x using basic algebra; then answer the question.&lt;br&gt;
(2) Using logical reasoning and simple mental arithmetic (fast -- and the THINKING is good brain exercise)&lt;br&gt;
In this sequence of consecutive integers (as in ANY arithmetic sequence), any number in the sequence is the average of the two numbers on either side.&lt;br&gt;
Since in this problem the sum of the first and third numbers is 60, that means the second number is 30.&lt;br&gt;
From there it takes little thinking at all to find the answer: 29, 30, 31, and 32.&lt;br&gt;
