Q. Which formula gives the general term for the sequence of positive odd numbers if we start the sequence at n = 0?
an = 2n + 1
an = 2n – 1
an = 2(n + 1)
an = 2(n – 1)
Q. Find the formula for the general term of the sequence
0, -10, 20, -30, 40, -50
if we start with n = 0.
an = 10(n – 1)
an = (-1)n – 110(n – 1)
an = (-1)n10n
an = (-1)n + 110n
Q. Give the formula for the general term of the sequence
starting with n = 1.
Q. Which of the following descriptions produce the sequence of natural numbers
1, 2, 3, 4,... ?
(I) an = n starting at n = 1
(II) an = n – 1 starting at n = 1
(III) an = n starting at n = 0
(IV) an = (n + 1) starting at n = 0

Q. Find the general term of the sequence
0.5, 2, 4.5, 8, 12.5, ...
starting with n = 1.
an = 1.5n – 1
Q. Which description produces the sequence 0,6,24,60,... ?
an = 6n2 starting at n = 0
an = 6n2 starting at n = 1
an = n3 – n starting at n = 0
an = n3 – n starting at n = 1
Q. Find the general term for the sequence
starting with n = 1.
