write the first 4 terms in the sequence defined by a

_{1}= -2, a

_{n+1}= a

_{n}/n!

this what I tried

a

_{2}= -2/1

a

_{3}= -2/2

a

_{4}= -1/6

Question 2

determine the following sequences converges or diverges

1- a

_{n}= sqrt(n^2 -3 )/ 5th rt(n^2)

what I would try is to divide both top and bottom by n^2 but here doesn't work that

way because the denominator is 5th rt

2- a

_{1}= 3, a

_{n+1}= (-1)^n+1 a

_{n}+ 3

a

_{2}= 6

a

_{3}= -3

but the ans would be ( 3,0,3,0,3,0)
