terms are 36, 90 and 16 respectively. Find
the forth term *


​

Answer 1

Given :

First, second and fourth term.

To Find :

Third term.

Assume:

The third term be x.

Solution :

➡ 16:24:x:54

➡ (16×54)=24x [the product of mean is equal to the product of extreme]

➡ x=864÷24

➡ x=36.

Answer:

The third term is 36.

Answer 2

Answer:

40

Step-by-step explanation:

We know that an extreme = Product of mean/ other extreme.

Here, the two means are 90 and 16,and the given extreme (fist term) is 36.

So, forth term= an extreme = 90×16

________

36

= 5 × 8 = 40
