Question

2. Find the 200th term of
the sequence:
3. 7. 11, 15, 19....

Answer 1

Explanation:

a =3 d=4 n=200

apply the general formula for the nth term

Answer 2

our initial is 3

a1=3

difference or d = 4

The general formula is an = a1+(n-1)*d

an= 3+(200-1)*4

an=3+199*4

an=3+396

an = 399

therefore the 200th item is 399
