Answer to Problem 68E
The sequence have a Quadratic model
Explanation of Solution
Given:Write the first six terms of the sequence beginning with the given terms . Then calculate the first and the second differences of the sequence . State whether the sequence has a perfect linear model o, perfect quadratic model or neither
The Given ,
Then Let the first difference be denoted by d and the second differences denoted by S
Then
First differences
Second differences
Since The second differences are equal therefore ,
The sequence have a Quadratic model
