¿Cuál serie numérica tiene como regla general Xn = 2n +1? a. 3, 5, 7, 9
b. 2, 4, 5, 8
c. 4, 6, 8,10
d. 2, 3, 4, 5

The series of numbers that correspond to the general rule of   is {3, 5, 7, 9}.

Step-by-step explanation:

We are given with the following series options below;

a. 3, 5, 7, 9

b. 2, 4, 5, 8

c. 4, 6, 8,10

d. 2, 3, 4, 5

And we have to identify what number series has a general rule as .

For this, we will put the values of n in the above expression and then will see which series is obtained as a result.

So, the given expression is ;

If we put n = 1, then;

If we put n = 2, then;

If we put n = 3, then;

If we put n = 4, then;

Hence, the series of numbers that correspond to the general rule of   is {3, 5, 7, 9}.

good luck!

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
