Find the nth term: 1, 4, 7, 10, 13, 16
choose the correct
n + 3 3n + 1 3n − 2 3n + 2

3n-2

Step-by-step explanation:

An= A1+(n-1)d

d=3

An= 1+(n-1)3

An= 1+3n-3

An= 3n-2

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
