Step-by-step explanation:

n

=a

1

+(n−1)d

⇒24=8+(5−1)d

⇒24−8=4d

⇒16=4d

⇒d=4

Now, insert the terms using d.

Therefore, the series is 8,12,16,20,24.

Answer 2

Answer:

We need to insert 3 arithmetic means between 8 and 24

Step-by-step explanation:

We know that aⁿ = a¡ + ( n - 1 ) d

=》24 = 8 + ( 5 - 1 ) d

=》24 - 8 = 4d

=》 16 = 4d

=》 d = 4

Now insert the terms using d .

Therefore , the series is 8 , 12 , 16 , 20 , 24
