Question

4. Show that the first two terms of the sequence an are zero and find a5 when
an=(n-1)(n-2)​

Answer 1

Answer:

A5=12

Step-by-step explanation:

As n>0 and first two terms are n=1 and n=2 we subtracted we get 0

So we can solve A5

A5=(5-1)(5-2)

= 4(3)

=12

So the value of A5 is 12

Hence the solution
