Question

The first four terms of a sequence are shown below: 7, 4, 1, −2 Which of the following functions best defines this sequence? plz help its 10 POINTS!!!!

Answer 1

x1 - 3 = x2
subtract 3 from the first value to get the second one

Answer 2

$T_n = a_1 + d(n - 1)$

$a_1 = 7 , d = -3$

$T_n =7 - 3(n - 1)$

$T_n =7 - 3n + 3$

$T_n =10 - 3n$
