Divide: 6 + 1 = 12 To verify the answer with a model, you could show
circles.
Each circle would be divided into
equal parts.
parts would be shaded.

two data sets with the same median will not have the same varaibility

step-by-step explanation:

thats not a system of equations, that is a solution

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
