No.A.P. First term =a : common difference=d S_n={2a+(n-1)d}*n/2

O.K. I went through it again . It is G.P.in the problem. I have to test my eyes.

Now the method stands corrected for G.P.

(5)sum of 1st 2011 terms=200

sum of next 2011 terms=380-200=180 R=180/200 =0.9

sum of next 2011 terms=180*0.9=162

Sum of first 6033 terms=200 +180+162=542

That is correct.

Bobbym, would you be fine with some adept calculus problems in my physics thread?

The integral of hope is reality.

May bobbym have a wonderful time in the pearly gates of heaven.

He will be sorely missed.

Hi;

You want to post them there or me to try and solve them?

You can do that but as you already know I never work on physics problems any more. But there are several others in here who will work on them.

At 96 one has physical problems ;not problems on physics.

Just the opposite in my case.

It is for those who are at 96, not for you.

Hmmm, you can believe that. I can not, nor will I try to convince you. It is not important what my age is and I am constantly amazed at people's reactions to it. Suffice it to say, due to many health techniques which were given to me by pappym's love of the east, I feel much younger that I am.

But back to the main part. I do not like physics and will not work on physics problems.
