Answer: -630
Step-by-step explanation:
Given the nth term of a sequence;
a(n)=a(n−1)⋅(−9) and the first term of the sequence a(1) as 35, the third term of the sequence can be gotten by using the formula at when n = 3
If n = 3 and a(1) = 35;
a(3) = 35(3-1)•(-9)
a(3) = 35×2×-9
a(3) = 70×-9
a(3) = -630
There the 3rd term of the series will give us -630 according to the nth term of the formula given.
The problem is about a recursive sequence where each term is the previous term multiplied by -9. After applying this rule twice, it is found that the 3rd term of the sequence is 243.
The problem provided indicates a recursive sequence, where each term is based on the previous term. The sequence is defined as a(1) = 3 and a(n) = a(n - 1) ⋅ (−9), which essentially means that each subsequent term is the previous term multiplied by -9.
To find the 3rd term, we apply this rule twice starting from the first term:
a(2) = a(1) * (-9) = 3 * (-9) = -27
a(3) = a(2) * (-9) = -27 * (-9) = 243
Therefore, the 3rd term of the sequence is 243.

The table gives the scores of 6 students from a class of 25 in a competitive exam. The point estimate of the mean score for the students is _____-
. (Round off your answer to the nearest tenth.)
Answer
593.3
Explanation
Mean is also called average. It represents the average mark of a given data.
For the question above, you to add all the marks of the students then you divide by the number of students.
Mean = (650+550+380+720+710+ 550)÷6
= 3,560 ÷ 6
=593.3333
Answer to the nearest tenth = 593.3
The point estimate of the meanscore for the students is 593.34 if the number of observation is 6.
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
We know,
Mean = (sum of observation)/(number of observation)
Sum of scores = 650+550+380+720+710+550 = 3560
Number of observation = 6
Mean = 3560/6 = 593.33 = 593.34
Thus, the point estimate of the meanscore for the students is 593.34 if the number of observation is 6.
