Study the graphs of the infinite below. Answer questions 4 through 11 by circling sequences the letters of all graphs, which the statement is true. ny, for None 4. The sequence is arithmetic. A B C D None 5. The sequence is geometric 6. The sequence is the Fibonacci sequence. A B C D None 7. The sequence sums to a finite number. None 8. The domain of the sequence is the set of A B C D None non-negative integers. A B C D None 9. Sequence(s) where one quantity changes at a constant rate per interval relative to another quantity. 10. Sequence(s) where one quantity changes at a A B C D None constant percentage rate per interval relative to another quantity. 11. One possible definition of the sequence is: A B C D None (n-2): a 1

Solution

4 . the sequence which is Arithmatic : A

the points lie on a straight line : y=mx+c , y₂ - y₁ = m( x₂- x₁) = m if x₂-x₁= 1

5 . the geometric sequence : B

the co domin is a set which consists of elements which has a commonratio r= 0.6

6 . Febonacci sequence : 1,1,2,3,5,8,13,----- (none)

7 . Sum to a finite no : B ,C

8 . sequence definition : f : (N) --> R hence the domain is always natural no hence positive

9 . Y= mx+c is the curve in A

y \' = m constant rate

10 None

11 . a₁ =1 , a₂ = 1 a₃ = 2 , a₄ = 4 ---( (D)
