Each time the value of n increases by 1, the value of an increases by a factor of 3. The 3rd choice is appropriate.
_____
When an expression like this one is written in plain text, it is appropriate (required) to put parentheses around the exponent that contains an arithmetic operation.
an = 4·3^(n-1)
If you leave off the parentheses, the expression no longer describes a geometric sequence.
Answer:
1st one is 20 2nd one is 21
Step-by-step explanation:
Answer: 72.6 cm
Step-by-step explanation:
Data: the length of the sides we know=13 cm, 16 cm 7.3 cm, 5.7 cm, 6.2 cm
The length of the side in the middle=x
The perimeter of the shape=x
Step one, Find the length of the missing side by adding then subtracting
5.7+6.2=11.9
16-11.9=4.1
x=4.1 cm
Reason: If you want to find the missing side, we know that the entire side down there is 16 cm so we just add 5.7 to 6.2 to get 11.9 and the amount of cm left after subtracting 11.9 from 16 will be the length(l) of the missing side.
Step two, add up all the sides
13+13+16+7.3+7.3+4.1+5.7+6.2=72.6
Reason: To find the perimiter of a shape, you add up all the sides and since we have all of the sides(some sides appear twice) we can just add them all together for the answer.
Also, don't forget the 'cm' in the answer
x=72.6 cm
I hope this helps!
