For the following geometric sequence, find the explicit formula. {1.-3,9 }

an = (-3)^(n-1).

Step-by-step explanation:

The formula for the nth term  an  = a1r^(n-1)  where a1 = first term and r = the common ratio.

In our series a1 = 1 and r = -3/1 = -3  so the explicit formula is:

1.  * (-3)^(n-1)

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

i cant answer this, theres no table. sorry man
