First, you know that Jackson (let call her J) scored 41 more points than L (Leslie). What we don't know is how many points L scored so we can use a variable that will be 'x'.
So the equation will be J=41+x.
We also know that the total points is 1,189.
To find out what x is we first subtract 1,189-41. We then get 1,148.
We are now left with 2x and 1,148 so we divide 1,148 by 2 and get 574.
574=x so now we can plug that in.
J= 574+41
Jackson scored 615 points and Leslie scored 574 points
(You can use bar modeling to do solve this problem. An example of bar modeling is shown below.

The first four terms of sequence is 20, -10, -40, -70
<em><u>Solution:</u></em>
Given that we have to find the first four terms of sequence
<em><u>Given recursive formula is:</u></em>
<em><u>To find the first term, substitute n = 1</u></em>
Thus the first term of sequence is 20
<em><u>To find the second term, substitute n = 2</u></em>
Thus the second term of sequence is -10
<em><u>To find the third term, substitute n = 3</u></em>
Thus the third term of sequence is -40
<em><u>To find the fourth term, substitute n = 4</u></em>
Thus the first four terms of sequence is 20, -10, -40, -70
