What are the first four terms of the sequence given by the formula below an=-2n+4

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
