We know that a1 = -1, and an = 2 * an-1.
We already know that the first time, a1, is -1. We're given the formula to find the next terms in the sequence.
For a given term in this sequence, it will be 2 times the last item in the sequence.
an = 2 * an-1
a2 = 2 * a2-1 = 2 * a1 = 2 * -1 = -2
a3 = 2 * a3-1 = 2 * a2 = 2 * -2 = -4
a4 = 2 * a4-1 = 2 * a3 = 2 * -4 = -8
a5 = 2 * a5-1 = 2 * a4 = 2 * -8 = -16
a6 = 2 * a6-1 = 2 * a5 = 2 * -16 = -32
Answer:
14(2×-1) is the factorization of this expression
Booooyyy dont even talk to meeee
Answer:
2/21+6/7 = 20/21
Step-by-step explanation:
2/21+6/7
=2/21+(6*3/7*3)
=2/21+18/21
=20/21
