Hi !
solution :-
Given , a = 2,
d = 5-2=3
Tn = 104
formula from nth term of an A.P
tn = a + (n -1)d
104 = 2 + (n-1)×3
104 = 2 + 3n-3
3n = 105
n = 105/3 = 35 term in this sequence of Ap .

Answer:
No. Of terms is 35
Step-by-step explanation:
a= 2
d=3
an- 104
an = a +(n-1)d
104 = 2 + (n-1) 3
104-2 = (n-1) 3
102/3= (n-1)
34+1 = n
N= 35
