Two terms of an arithmetic sequence are a5=23 and a20=98. find the first 60 terms of the sequence

Step-by-step explanation:

The nth term of an arithmetic sequence is obtained using the formula:

Given that:

a_n=a+(n-1)d

Therefore, the first 60 terms of the sequence are:

it would be a on edgenuit y

the diagram below is your final answer

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.
