Correct Answer - Option 3 : 11
Concept:
nth term of A.P are a, a + d , a + 2d, . . . . ,a + (n-1)d .
Tn = a + ( n - 1 ) d
Where a = first term and d = common difference
Calculation:
Two-digit numbers are divisible by 8 are 16, 24 . . . . 96
Series of AP 16, 24 . . . . 96
As we know that , Tn = a + ( n - 1 ) d
⇒ 96 = 16 + ( n - 1 ) 8
⇒ 80 = ( n- 1 ) 8
⇒ 10 = n - 1
⇒ n = 11.
The correct option is 1
