Answer 2

31 : 69 :: 351 : 709

• 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 generalization, 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,

31 : 69 :: 351 : ?

Now, if we consider the second numbers of the relations,

$69 = 31.2+7$, that is, multiplying 2 with the first term of the relation and adding 7 with the product, we get the second term of the relation.

Similarly, we get,

$351.2+7 = 709.$

Hence, the missing number is 709.
