In a sequence, each term starting with the third onward is defined by the following formula an=an−1−an−2an=an−1−an−2, where n is an integer greater than 2. If the first term of that sequence is 3 and the second term is 4, what is the value of the 70th of that sequence?  Pick.
A) −4 B) −3 C) −1 D) 3 E) 4
Given an=an−1−an−2an=an−1−an−2   a3 = a2 - a1 =&gt; 4-3=

1.   a4= -3   a5 = -4   a6 = -1   a7 = 3   a8 = 4   a9 = 1   a10 = -3   So pattern is 3,4 ,1,-3,-4,-1,3,4,1 and -3 - first term terms...   70th term is -3.   Answer :option −3
