Write the first 4 terms of the sequence defined below. an={−6,ifn=1an−1+5,ifn>1
A.−6, −1, 5, 10
B.−6, −30, −150, −750
C.−6, −11, −16, −21
D.−6, −1, 4, 9

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

a 270° rotation about point p says on e d g e n u it y (had to space it out because it says it's a misspelling so i couldn't submit it
