Question

3) Which sequence is modeled by the graph below?

coordinate plane showing the points (1, 2); (2, 2); (3, 2); (4, 2)

A) an = 2(n − 1)1

B) an = 2(1)n − 1

C) an = 2 + (1)n − 1

D) an = (2)(n − 1)


4) Find the sum of the summation of 2 i minus 9, from i equals 3 to 10.

A) 52

B) 26

C) 13

D) 32

Answer 1

The sequence that is modeled by the graph below having the set of ordered pairs
(1, 2); (2, 2); (3, 2); (4, 2)
is 
D) an = (2)(n − 1)

The sum of the summation of 2 i minus 9, from i equals 3 to 10
-3 + - 1 + 1+ 3 + 5 + 7 + 9 + 11 =  32

The answer is
D) 32
