Corey added stickers to his party invitations. he put the same number of stickers on 7 invitations. which expression shows the number of stickers corey put on each invitation? let the variable s stand for the number of stickers corey started with.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
