Find the formula for the sequence.
-5,-1,3,7,......
Answers:
A. An= n-5
B.An=4n-9
C.An=-4n+9
D.An=-5n
+128661 The "formula" for the nth term of the series is given by:
an = a1 + d(n -1) where a1 is the first term, (-5), and d is the common difference between successive terms = (4)..so we have
an = -5 + 4(n - 1) = -5 + 4n - 4 = -9 + 4n ....or just... 4n -9 .... so...the answer is (B)
