The sequence which is an arithmetic sequence is -2, -8, -14, -20, -26,

Arithmetic sequence is given by

  • an = a + (n - 1)d

where

n = nth term

a = first term

d = common difference

  • -48, -24, -12, -6, -3, ...

a = -48

d = -24 - (-48)

= -24 + 48

= 24

a3 = -48 + (3-1) 24

= -48 + (2)24

= -48 + 48

= 0

False

  • -2, -8, -14, -20, -26,

a = -2

d = -8 - (-2)

= -8 + 2

= -6

a3 = -2 + (3 - 1) -6

= -2 + (2)6

= -2 - 12

= -14

True

  • 1, 6, 12, 18, 24, ...

a = 1

d = 6 - 1

= 5

a3 = 1 + (3-1)5

= 1 + (2)5

= 1 + 10

= 11

False

  • -2, 6, -10, 14, -18,

a = -2

d = 6 - (-2)

= 6 + 2

= 8

a3 = -2 + (3-1)8

= -2 + (2)8

= -2+16

= 14

False
