Which equation represents the relationship? y = StartFraction 5 Over 4 EndFraction x
y = StartFraction 4 Over 5 EndFraction x
y = StartFraction 5 Over 4 EndFraction x + 10
y = StartFraction 4 Over 5 EndFraction x + 55

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

d is ur answer hopes this i dont really know how to explain it to u.
