Answer:
c 70%
Step-by-step explanation:
20 into 14 = 70%
C) 70%
To find his percentage we take part over total
14/20
We want it over 100, so multiply the top and bottom by 5
14*5
---------
20*5
70/100
Percent means out of 100
so we have 70 percent
70 %
The numbers slowly decrease by 4 so we can determine that the 40th sequence is -70.
