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:
Marks age is 24.
Step-by-step explanation:
If Sunita's age is x then Mark's age = 4x/3 years.
In 12 years their ages will be (x + 12) and 4x/3 + 12.
So (x + 12) / (4x/3 + 12) = 5/6
6(x + 12) = 5(4x/3 + 12)
6x + 72 = 20x / 3 + 60
72 - 60 = 20x/3 - 6x Multiply through by 3:
216 - 180 = 20x - 18x
2x = 36
x = 18 = Sunita's age
So Mark's age is 18 * 4/3 = 24 years.
