An=A1 +(n-1)d
The Equation of an Geometric Sequence is
An=A1+r n-1
The Objective is to reconize and extend an arithmetric Sequence. Find a given term of an arithmetric sequence.
In Arithmetric Sequence its either adding or subtracting
In Geometric Sequence its mutiply or divide
Examples of Arithmetric Sequence
1,3,6,9,12 Its arithmetric because every number is added by 3
4,6,12,17 Its not Arithmetric because all the numbers are added by a different number every time
Examples of Geometric Sequence
2,4,8,16 Is geometric because its multiplied by the same number
6,12.48,144 Is not Geometric because its mutiplied by a different number each time
