Hi all. Any help on these annoying questions will be much appreciated!
1) The second term of an AP is 4.5 and the tenth term is -7.5. Find the sum of the first ten terms.
2) For the series √2 + 1 + 1/√2 + ...
a) Find the sum to ten terms of the series
b) what is the difference between the sum to ten terms and the sum to infinity?
3) A ball is dropped from a height of ten metres. It continually bounces back up to a height equal to four-fifths of its previous height. Find the total distance traveled by the ball.
I am quite bad at this so any help or tips from anyone will be gladly accepted! Cheers!
