A1=24
<span>n=500(seq #) </span>
<span>d=how much u add each time=6 </span>
<span>a(n)=24+(500-1)(6)=3018</span>
Answer:
12
Step-by-step explanation:
Use the Pythagorean theorem which is a^2 + b^2 = c^2
c is hypotenuse and a and b are the legs
we need to find a^2 so
a^2 + 16^2 = 20^2
a^22 + 256 = 400
then subtract 256 from 400
a^2 = 144
square root 144
= 12
