Answer 2

Question

what are the first four terms of the sequence given by the formula below?
`a_(n)`=-2n+4

A) -6, -8, -10, -12

B) -2, 0, 2, 4

C) 2, 0, -2, -4

D) 6, 8, 10, 12

Answer & Step-by-step explanation:

`a_(n)`=-2n+4 ; where n is the sequence number or order.

`a_(1)` = -2(1) + 4

`a_(1)` = -2 + 4

`a_(1)` = 2

`a_(2)` = -2(2) + 4

`a_(2)` = -4 + 4

`a_(2)` = 0

`a_(3)` = -2(3) + 4

`a_(3)` = -6 + 4

`a_(3)` = -2

`a_(4)` = -2(4) + 4

`a_(4)` = -8 + 4

`a_(4)` = -4

So the first four terms of the sequence are: C) 2, 0, -2, -4
