The recursive formula for an, the nth term of the sequence is An = -A(n-1)/2 where A1 = 4
How to write a recursive formula for an, the nth term of the sequence?
The sequence is given as:
4, -2, 1, ....
In the above sequence, we have
A1 = 4
Also, the subsequent terms are gotten by dividing the previous terms by -2
This is represented as
An = -A(n-1)/2
Hence, the recursive formula for an, the nth term of the sequence is An = -A(n-1)/2 where A1 = 4
