Answer:
7, 10, 13
Step-by-step explanation:
1) n = 1: 3(1) + 4 = 3 + 4 = 7
2) n = 2: 3(2) + 4 = 6 + 4 = 10
3) n = 3: 3(3) + 4 = 9 + 4 = 13
Answer:
fourth number is 9
Step-by-step explanation:
let 'x' equal the fourth number
(5+7+7+x)/4 = 7

19 + x = 28
x = 9
<span>There is a decrease of 20% from ÂŁ800 to ÂŁ640.
A change from 800 to 640 represents a negative change (decrease) of -20% Using the formula :
Percent change = [(800 - 640) / 800] x 100 = -20 % (decrease)
800 is the old value and 640 is the new value. In this case we have a negative change (decrease) of -20 percent because the new value is smaller than the old value.</span>
Think about it think 6x5 or higher then you will get you answer by doing that
