Given : 13:182::25:650::18:342::20:?

To Find : the last number according to this series.

Explanation :

Logical reasoning consists of a logical level of analysis which is help to find the correct answer. There are three types of reasoning these are deductive, inductive, and abductive.

for this problem the logic is

$\begin{aligned}&13^{2}+13=169+13=182 \\&25^{2}+25=625+25=650 \\&18^{2}+18=392 \\&20^{2}+20=400+20=420\end{aligned}$

Answer 2

Answer:

The final answer is 420 for the series given.

Step-by-step explanation:

Series is a patten by numbers or objects.

We are given that:

13:182::25:650::18:342::20:?

We need to find the last number according to this series.

It requires logical reasoning which can be of three types of reasoning these are deductive, inductive, and adductive.

For this problem the logic used is:

13² + 13 = 169 + 13 = 182

25² + 25 = 625 + 25 = 650

18² + 18 =324 + 18 = 342

Similarly:

20² + 20 = 400 + 20 = 420.

Therefore, according to this series, we get the answer as 420.
