Re: Series and Progressions
Hi;
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.

Re: Series and Progressions
Hi;
The solution SP#181 (two parts) are correct. Neat work, bobbym!
SP#182. Write the first four terms of the Arithmetic Progression, when the first term 'a' and common difference 'd' are given as follows:
(i) a = 4, d = -3.
(ii) a = -1, d = 1/2.
