Answer:
The common ratio is
The next term in the sequence is 2
Step-by-step explanation:
In a geometric sequence, the common ratio is the constant value you multiply a term by in order to find the value of the following term. Therefore, it is mathematically calculated as the quotient between a term and the term immediately before it. And it is in fact That is:
common ratio
This quotient should be true for any two consecutive terms in the sequence.
so using the first two terms, we find:
You can test that this common ratio is true for all other terms listed:
So now, in order to find the term that follows, all we need to do is to multiply the last term given (8) by this common ratio:
Given:
The reasoning problem is
42=164, 73=499, 51= 251, 29=?
To find:
The missing value.
Solution:
In the given reasoning problem, we need to square each digit then write them combinedly.
On combining these two, we get
Similarly,
Using this pattern, we need write the square of 2 and 9 combinedly to find the value of 29.
Therefore, the missing value is 481.
