ARITHMETHIC PROGRESSION
1 An arithmetic progression is a number sequence where the difference between each term after the first term and the preceding term is a constant. This constant is know as the common difference,(d).

GEOMETRIC PROGRESSION1 A geometric progression is a number sequence where each
term after the first term is obtained by multiplying the preceding term by a constant know as the common ratio, r.
r = Tn + 1 , Tn
Where Tn +1 = (n + 1)th term and Tn = nth

LINE OF BEST FIT
1 The line of fit is a straight line that has the following properties:• Passes through as many point as possible• The number of point that do not lie on the straight line draw should
be more or less the same o n both sides of the straight line.
For example: y
x

APPLICATION OF LINERA LAW TO NON-LINEAR FUNTIONS
1 A non-linear funtion is a funtion that has one or more variable, x or y, which are not in the first degree. For example
y = mx + c2 A non-linear funtion that consists of variable,
x and y, (a curve line graph) can be reduce to the linear form
