Answer:
a1 = 6 and an = an-1 - 5
a2 = a2-1 - 5 = a1 - 5 = 1
a3 = a3-1 - 5 = a2 - 5 = -4, etc
Step-by-step explanation:
( original - new)/ original * 100 %
Take the new amount
Subtract the original amount
( original - new)
Then divide by the original amount
( original - new)/ original
Multiply by 100% to get the percent loss

Pythagorean Theorem a^2 + b^2 = c^2
11 is 110 for x and y
12 is 90 degrees for x and y
13 is also 90 degrees for x and y
