Question 1185225
<br>
The dollar amounts form an arithmetic sequence of 150 terms with first term 1.25 and common difference 0.15: 1.25, 1.40, 1.55, ...<br>
The sum of the terms of an arithmetic sequence is<br>
Sum = (number of terms) times (average of all the terms)<br>
In an arithmetic sequence, because of the constant spacing between terms, the average of all the terms is the average of the first and last terms.<br>
So to find the answer to the question, you can do the following:<br>
(1) determine the 150th (last) term: first term plus 149 times the common difference;
(2) find the average of the first and last terms; and
(3) multiply that average by the number of terms, 150.<br>
