4,12,6,18,12,36,30...
Answers
Answer:
36 & 90
Step-by-step explanation:
Explanation:
the next 2 number in series we need to divide the series into 2 different series
First series : 4 , 6, 12, 30 ??
Second Series : 12,18,26, ??
So we need to see for the pattern for those series in order to find the next two number , we can do this by finding the difference or division , multiplication logic whatever may apply :
Pattern of Series 1 :
6 divide 4 : 1.5
Next number i.e 12 divided by 6=2
Next number i.e 30 divided by 12 =2.5
So series is going in multiples of 1.5, 2, 2.5, 3 , so on
So first series will look like
4 , 6, 12, 30, 30x3 =90
Pattern of Series 2 : 12,18,26, ??
Its simple Adding numbers with iterative logic (i.e 6, 8, then followed by 10, 12)
Series will be like 12,18,26,36.
For the next two numbers : Series will be like 4, 12, 6, 18, 12, 26, 30, 36, 90
Correct question is "What is the next term of the series 4,12,6,18,12,36,30...?"
Answer:
Required next term is 90.
Step-by-step explanation:
Given series is 4,12,6,18,12,36,30...
Here we want to find next term.
This is a problem of General inteligence of Mathematics.
If you look it carefully then you can see that this series maintain a sequence.
Here,
First term is 4
and second term is (4×3) = 12
Again 3rd term is 6
and fourth term is (6×3) = 18
And fifth term is 12 and sixth term is (12×3) = 36
So it is clear if p is a term then next term of p is (3×p)
Here also given seventh term is 30.
So we can say that number of eight term is (30×3) = 90.
This is a problem of Algebra.
Some important Algebra formulas.
(a + b)² = a² + 2ab + b²
(a − b)² = a² − 2ab − b²
(a + b)³ = a³ + 3a²b + 3ab² + b³
(a - b)³ = a³ - 3a²b + 3ab² - b³
a³ + b³ = (a + b)³ − 3ab(a + b)
a³ - b³ = (a -b)³ + 3ab(a - b)
a² − b² = (a + b)(a − b)
a² + b² = (a + b)² − 2ab
a² + b² = (a − b)² + 2ab
a³ − b³ = (a − b)(a² + ab + b²)
a³ + b³ = (a + b)(a² − ab + b²)
