Answer:
21
Step-by-step explanation:
You add up the two people until u get the number 259
Take the sequence;
<span>9, 12, 19, 30, ...</span>
Therefore the whole formula for the nth term is;
<span>2n^2 + 3n - 10</span>
You look to the right when you round
A centimeter ruler is more precise because it is a smaller measurement
Yes, there is a difference between 51 and 51.0 because you now know that there is a 0 behind 51 and it was not rounded to become 51.
Units can be helpful because they can help you picture the world problem or convert any numbers like feet to inches properly.
Answer:
The next two terms after a1 is
-6 and then 18
Step-by-step explanation:
Geometric sequence means your pattern for the terms is multiplication by the same number.
So a1 is the first term and r is your common ratio.
The common ratio is what you are multiplying by each time to figure out the next term.
So the geometric sequence goes like this:
a1 , a1*r , (a1*r)*r or a1*r^2 , a1*r^3 ,....
So anyways you have
first term a1=2
second term a2=2(-3)=-6
third term a3=-6(-3)=18
And so on...
