Answer:

Step-by-step explanation:
a1 = 8
a9 = 56
Using formula for finding nth term of arithmeric sequence

We have to find 24th term, therefore n = 24
is the first term but we are missing d
d is the difference between the two consecutive terms, lets calculate it first
a9 = 56
Using the above given formula for finding d
put n = 9, a9= 56

56 = 8 + 8d
8d = 48
d = 6
Getting back to main part of finding 24th term
n = 24, d = 6, a1 = 8
put values in nth term formula

Answer: (14.4 x 8)-4
Step-by-step explanation:
add 2.8 and 11.6 and multiply 8 your answer will be 115.2 but when you subtract it with the four you will get the same thing when you calculate the regular problem.I hope this help
