what is a possible value for the missing term of the geometric sequence? 44, , 1584,...
the way you solve a geometric sequence is that you start with a number and you multiply a certain number to get the second number. multiply that with the certain number to get the third number.
so basically if we start a geometric sequence that starts with 1 and we keep multiplying by 3, we get the sequence of 1,3,9,27,81....
this question is different in that you start with a 44 and you are given the third number, not the second number. so obviously, if you multiplied by a certain number to the 44, you would get the second number. you can multiply that by the certain number again to get the third number, which is 1584
given that our starting number is X and we keep multiplying by Y, our sequence would look like this: X, X*Y, X*Y^2
we know that X = 44 and X*Y^2 = 1584. thus if we divide 1584 by 44, we get Y^2 which is 36
we want to know the second number, which is X*Y. Y^2 is 36 so Y = 6 OR -6. that is why the answer would be 264 and/or -264
now I can do it myself thank so much :)
thank you
