Step-by-step explanation:
First off, you want to find the whole number in square root form
1 = √1
2 = √4
3 = √9
4 = √16
5 = √25
You want to find which to numbers √7 is in between
7 is between 4 and 9 so the √7 is in between √4 and √9 which means that √7 is between 2 and 3
The second one is your answer
I hope this helps!!!
Answer:
Step-by-step explanation:
In a geometric sequence, consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as
an = a1r^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the given sequence,
a1 = - 5
r = 15/- 5 = - 3
Therefore, the explicit rule for this sequence is
an = - 5(- 3)^n - 1
