8. Make a generalization based on the numerical sequence below :


      5 = 2 + 3(1)2
    14 =2 + 3(2)2

    29 =2 + 3(2)2

    50 =2 + 3(2)2

A 2 + 3n , n= 1,2,3,…

B 2 + 3n2 , n= 1,2,3,…

C n + 3n2 , n = 1,2,3,…

D n – 2n2 , n = 1,2,3,…



9. Which of the generalization below represents the numerical sequence -2 , -6 , -10 ,… where n= 1,2,3,…

A 2 – 4n

B 3 – 4n

C 2n2 – 1

D -1 – 3n



10. Which of the following is the numerical sequence for 3n2 – 1 with n= 1, 2, 3,…?

A 2, 11 , 26 , 47 ,…

B 4 , 35 , 80 , 143 ,…

C 2 ,11 , 27 , 47 ,…

D 10, 11,26 , 48 ,…
