Step-by-step explanation:
Answer:
16 runs.
Step-by-step explanation:
We have been given that on the first day of baseball tournament Jessie scored 2 runs. On the second day, 4 runs. On the third day, 6 runs.
We can see that runs scored by Jessie form an arithmetic sequence, where each successive term is 2 more than the previous term.
Since we know that formula for nth term of an arithmetic sequence is:
, where,
,
,
,
.
Since on the first day Jessie scored 2 runs, so
and difference between two consecutive terms is 2 (4-2=2), so d will be 2.
Upon substituting our values in arithmetic sequence formula we will get,
![a_n=2+(n-1)*2](https://tex.z-dn.net/?f=a_n%3D2%2B%28n-1%29%2A2)
![a_n=2+2n-2](https://tex.z-dn.net/?f=a_n%3D2%2B2n-2)
![a_n=2n](https://tex.z-dn.net/?f=a_n%3D2n)
Therefore, formula for nth term of sequence representing number scored by Jessie on the baseball tournament is
.
Let us find the 8th term of sequence by substituting n=8 in our sequence formula.
![a_8=2*8](https://tex.z-dn.net/?f=a_8%3D2%2A8)
![a_8=16](https://tex.z-dn.net/?f=a_8%3D16)
Therefore, Jessie should score 16 runs on the eighth day of baseball tournament.
