Ageometric sequence {an} is defined by the function

f(1) = a1 = 6 and f(n) = an = (1.2)*f(n - 1) for n ≥ 2.

find f(38).
a)273.6
b)326.26
c)5103.3735
d)6124.0482

ANSWER

C)5103.3735

EXPLANATION

The recursive definition of the given sequence is;

and

The explicit definition is

We substitute n=38 to obtain:

The correct choice is C.

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
