SUM OF ARITHMETIC PROGRESSION (A.P)

UNLOCK THE SECRETS OF MATHEMATICS - selar.co/7ml7
The sum of an Arithmetic Progression is adding up the number of terms of a given sequence or series.
The formulae is of two types:
- The one where you are given the first term (a) and the last term (L).
- The one where you’re given the number of terms (n), the common difference(d) and the first term (a). This is the formula you will find in this video.
Feel free to ask for an example where the first formula is used and it will be provided.

Ma what if we have something like this .. the sum of the 8 term of am AP is 90 , and it's first term is 6 . What is the common difference?? Am a little bit confused 😢

[@Somng]

Don’t be confused. Begin by writing the formula for the “sun of AP”.
After which you substitute the values n=8, S = 90 and a = 6.
You’d find the common difference (d)
