<em><u>The explicit equation for the nth term of the geometric sequence 3584, 896, 224 is:</u></em>
<em><u>Solution:</u></em>
Given that we have to find the explicit equation for nth term of geometric sequence
<em><u>Given sequence is:</u></em>
3584, 896, 224
A geometric sequence has a common ratio
Let us find the common ratio. Divide each term by the previous term.
Thus the common ratio is 0.25
<em><u>The formula for nth term of geometric sequence is given as:</u></em>
Where,
is the nth term of sequence
a is the first term of sequence
r is the common ratio
Here in given sequence 3584, 896, 224
first term = a = 3584
common ratio = r = 0.25
Therefore,
"n" is a natural positive number greater than or equal to 1
Thus the explicit equation to find nth term is found
Answer:
Mean
Step-by-step explanation:
Mean is the average of all results.
Step 1 : Identify the formula of calculating mean
Mean = <u>Sum of all data</u>
Number of data
Step 2 : Substitute the values in the formula
Mean = <u>10 + 15 + 25 +75 + 75 + 77 + 80 +83 + 85 + 90</u>
10
Mean = <u>615</u>
10
Mean = 61.5 marks
