Find a formula for the general term an (not the partial sum) of each infinite series (with starting point of n = 1.) (a) 5 4 + 5 16 + 5 64 + 5 256 + an = 5 4n (b) 1 1 + 5 2 + 25 4 + 125 8 + an = ( 5 2)n−1 (c) 1 + 7 1 − 2 + 7 2 · 1 + 3 + 7 3 · 2 · 1 − 4 + 7 4 · 3 · 2 · 1 + an = (−1)n−1 n+7 n! (d) 8 12 + 1 + 3 22 + 1 + 8 32 + 1 + 3 42 + 1 + an = 15−(1)n−1 2(n2+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
