You line up the decimal points so that similar place values are lined up. it will be easier to add them.
First u do a squared +b squared =c squared aka pythagorean theorem then so u already have c squared so you would do 5x5=25 and 13x13=169 so then the equation would be 25+?=169 then do 169-25 which equals 144 and then do the square root of that which is 12 THE ANSWER IS 12
We notice it diviides by 3 each time or multiplies by 1/3
common ratio is 1/3
first term is 648
so next 3 terms are 8, 8/3, and 8/9
rule is an=648(1/3)^(n-1)
