Sequences: Because We'd Rather Start Counting from Zero Quiz
Think you’ve got your head wrapped around
? Put your knowledge to
the test. Good luck — the Stickman is counting on you!
Q. A sequence is
a list of numbers.
an infinite list of numbers.
an infinite list of terms separated by commas.
a list of numbers where the
n th number is given by a mathematical formula.
A sequence is defined by
be the decimal expansion of
Q. Which formula gives the general term for the sequence of positive odd numbers if we start the sequence at n = 0?
a = 2 n n + 1 a = 2 n n – 1 a = 2( n n + 1) a = 2( n n – 1)
Find the formula for the general term of the sequence
0, -10, 20, -30, 40, -50
if we start with
n = 0.
a = 10( n n – 1) a = (-1) n 10( n – 1 n – 1) a = (-1) n 10 n n a = (-1) n 10 n + 1 n
Give the formula for the general term of the sequence
n = 1.
Which of the following descriptions produce the sequence of natural numbers
1, 2, 3, 4,... ?
a = n n starting at n = 1 (II) a = n n – 1 starting at n = 1 (III) a = n n starting at n = 0 (IV) a = ( n n + 1) starting at n = 0
I and II
I and IV
II and III
III and IV
Find the general term of the sequence
0.5, 2, 4.5, 8, 12.5, ...
n = 1.
Q. Which description produces the sequence 0,6,24,60,... ?
a = 6 n n 2 starting at n = 0 a = 6 n n 2 starting at n = 1 a = n n 3 – n starting at n = 0 a = n n 3 – n starting at n = 1
Find the general term for the sequence
n = 1.
