This is a geometric sequence and the common ratio is 0.5.
So, the next term will be 2.75.
Answer:
a=6
b= -15
Step-by-step explanation:
third term --> n=3
a(3)^2 + b(3) =9
9a+3b=9
3(3a +b)=9
3a +b=9/3=3
3a + b=3 ------eqn1
sixth term n=6
a(6)^2 +6b =126
36a +6b=126
6(6a+b)=126
6a + b =126/6=21
6a + b=21----------eqn 2
eqn2 - eqn 1
(6a-3a) +(b-b) =21-3
3a=18
a=18/3=6
sub a= 6 into eqn2
6(6)+b=21
36 +b =21
b=21-36= -15
Answer:
Yes the are similar, they are similar because they have the same angles. They are the same shape as each other, just dilated.
Okay gotcha bye you need help with math homework
The quotient is the result of dividing..
85/0.25 = 340 <===
