The correct option is A 86
The first term of the pattern is 7.
The second term is 13.
The third term is 20, which can be obtained by adding the first and second term:7+13=20.
The fourth term is 33, which can be obtained by adding the second and the third term: 13+20=33.
The fifth term is 53, which can be obtained by adding the third and the fourth term: 20+33=53.
This means the sixth number in the pattern can be calculated by adding the fourth and fifth terms. So, the sixth term of the pattern will be 33+53=86.
