Answer:
see below
Step-by-step explanation:
70 + 70 = 140.
We know that 80 is 10 more than 70
the answer to 70+80 must be 10 more than the answer to 70+70 =140
so 140+10 = 150
Answer:
you would just add 10 to 140
Answer: -8
Step-by-step explanation:
We must remember that, in geometric sequences, the ratio between the consecutive terms is constant.This is called "Common ratio" and is represented with "r".
We need to find the common ratio of this geometric sequence:
Divide one term by the previous term:
Then, the next term asked in the exercise can be found by multiplying -4 by 2.
Therefore, this is:
Answer:
-8
Step-by-step explanation:
r=2
so multiply third term by 2
17 + 330 • 20 ÷ 10² ÷ 2 – 14
