Naledi climbed up a mountain. Her initial altitude was 40 meters above sea level, and it increased by 10 meters each hour. Let )g(n)be Naledi's altitude at the beginning of the nth hour of her climb. G is a sequence. What kind of sequence is it?

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
