Answer:

95 is the correct answer

Answer 2

95

The missing number is 15(6)84,30(8)152,20(5)95.

Step-by-step explanation:

Given:

Find the missing number in 15(6)84,30(8)152,20(5)?

To find:

The missing number in the sequence.

Solution:

The numerical sequence follows a multiplication by the number of the brackets and thus subtracted from the resulting value.

15(6)84⇒20(5)?

This part follows the sequential order must be multiplication of brackets value and subtracts the resulting value with the number of the brackets.

15(6)84⇒(15×6)-6

           ⇒90-6=84

30(8)152

This follows a pattern of the last number of the first term 84 is added with brackets number and 30(8) are divided by 2 i.e [(30÷2)(8÷2)].

The resulted term is added with (84+8=92)

30(8)152⇒(84+8)+[(30÷2)(8÷2)]

               ⇒92+(15×4)

               ⇒92+60

               ⇒152

20(5)?⇒ (20×5)-5

          ⇒95.

Hence,

The missing number in the sequence is 15(6)84, 30(8)152, 20(5)95
