notice that the values of an increase by 2
so we need something like ?? = ?? + 2
there is only one such pattern and it is B
It should have been:
an = an-1 + 2, a1 = -1 , n>1
that last part must be included, or else the sequence has no start
Look at the sequence in this table
n 1 2 3 4 5 ...
An -1 1 3 5 7 ...
Which function represents the sequence?
A) an = an - 1 + 1
B) an = an - 1 + 2
C) an = 2an - 1 -1 ***
D) an = 2an -1 - 3
