23X5 +4 = 119
119X6 +5 = 719
719X7 +6 = 5039

Answer 2

Answer: The missing number is 5039.

Step-by-step explanation:

The first number is 1 then it is 5.

To get 5 from 1, one must multiple 1 with 3 and add 2 i, e; 1×3+2 is equal to 5.

The second number is 5 then it is 23.

To get 23 from 5, one must multiple 5 with 4 and add 3 i, e; 5×4+3 is equal to 23.

The third number is 23 then it is 119.

To get 119 from 23, one must multiple 23 with 5 and add 4 i, e; 23×5+4 is equal to 119.

The fourth number is 119 then it is 719.

To get 719 from 199, one must multiple 199 with 6 and add 5 i, e; 199×6+5 is equal to 719.

The missing number is 5039.

To get 5039 from 719, one must multiple 719 with 7 and add 6 i, e; 719×7+6 is equal to 5039.
