The figure below shows the number of dots in each of the first four terms of a pattern. image 3946d177031641899e8a9055b29f185e

Which of these can be used to determine
N
, the number of dots, given
t
, the number of the term in the pattern?

N
=
4
(
t
−
1
)

N = 4 ( t − 1 )

N
=
3
t
+
1

N = 3 t + 1

N
=
3
(
t
−
1
)
+
1

N = 3 ( t − 1 ) + 1

N
=
3
t
+
2
