proportion are 42,36 and 35. Find the fourth term​

Answer 1

Answer:

30

Step-by-step explanation:

Let the 4th term be x

product of extream=product of mean

so,42×x=36×35

so,x=36×35÷42=30

HENCE THE 4TH TERM WILL BE 30

Answer 2

$\huge\mathfrak\blue{Answer:}$

Given:

The first three terms of proportion

42, 36 and 35.

To Find:

We need to find the fourth term.

Solution:

Let the fourth term be x.

According to question:

42 : 36 : : 35 : x

we know that product of means = product of extremes.

42 × x = 36 × 35

42x = 1260

x = 1260/42

x = 30

Hence, the fourth term of proportion is 30.
