Solve these equations: 1. 2(n+1)+1=(n-5)+(n-2) 2. 3(n-1)-2=4(n--1)

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

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.
