Find the sum of the predecessor of the predecessor of 2987 and successor of the greatest 3 digits number is

3985

Step-by-step explanation:

Note: predecessor means a number before for example  predecessor of 4 is 3. Similarly, successor is a number after for example the successor of 4 is 5.

The  predecessor of the predecessor of 2987  = 2987-2 = 2985

Let 2985 be x

The greatest 3 digit number = 999

And the successor of the greatest 3 digits number would be = 999+1 = 1000

let 1000 be y

We have find  the sum of x and y

= 2985+1000

= 3985

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
