What are the first four terms of the sequence given by the formula below an=-2n+4
2 answers:
An = -2n + 4 ; where n is the sequence number or order.
a1 = -2(1) + 4
a1 = -2 + 4
a1 = 2
a2 = -2(2) + 4
a2 = -4 + 4
a2 = 0
a3 = -2(3) + 4
a3 = -6 + 4
a3 = -2
a4 = -2(4) + 4
a4 = -8 + 4
a4 = -4
So the first four terms of the sequence are: 2, 0, -2, -4
The answer is:
<h2>
2, 0, -2, -4</h2>
