Answer 2

Answer:

54 is the correct answer

Given:

78, 66, _ 42,30

To find:

the missing number

Solution:

here, we have been given an incomplete series and we need to find out the missing number. on careful observation of the given series, we can see that the numbers are being reduced by 12 from left to right.

let the missing number be X.

78, 66, X, 42,30

78-12 = 66

66- 12 = X

X = 54.

to verify, let's subtract 12 from 54.

X- 12 =  42

X = 42 + 12 = 54

hence, verified.

Hence, 54 is the correct answer.
