{15, 16, 17, ?, 23}

arithmetic sequence: a sequnce in which the diffrence between any two consecutive terms is the same

step-by-step explanation:

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
