Sorry, your description makes little sense to me.

Is there a regularity behind this sequence? Do you need to find this regularity? Or are you givenexmple: start value zero next value -2 then 1 then -3 ,2,-2, -2,-3,2,-3,1,-1,1,-3,1,-8somearbitrary sequence?

What does it mean that a circle "is started from the zero point"? Its center is the origin? It passes through the origin? What is the initial radius of the circle?am using a caliper to draw a circle started from the zero point

Which line? Which circle?the line that start from zero will not touch the inner circumference of the circle

Which problem?since am using the graphical solution of this problem

Solution to what? Y value of what?could any one help in a numerical solution that can help me to find the y value ?
