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

Answer 2

The answer would be C) 2, 0, -2, -4
