Question

6,20,?,200,606,1820​

Answer 1

6×3+2=20

20×3+6=66

66×3+2=200

200×3+6=606

606×3+2=1820

ans=66

Answer 2

The missing number is 66.

• A series in mathematics is essentially a description of the process of successively adding an infinite number of quantities to a specified initial quantity. A significant component of calculus and its generalisation, mathematical analysis, is the study of series.
• Most branches of mathematics use series, including combinatorics, where generating functions are used to explore finite structures. In addition to being widely utilized in mathematics, infinite series are also used extensively in physics, computer science, statistics, and finance, among other quantitative fields.

Here, according to the given information, we are given that,

6,20,?,200,606,1820​.

Now, the first term is 6.

$6.3+2 = 20.$

Now, proceeding with the second term, we get,

$20.3+6 = 66.$

Again, $66.3+2 = 200.$

Again, $200.3+6 = 606.$

Hence, the missing number is 66.
