Answer 1

answer : option (E) none of these.

first AP sequence is ; 2 , 5 , 8, 11 , .... 98

first term, a₁ = 2 and common difference, d₁ = 3

2nd AP sequence is ; 3, 8, 13, 18, 23.... 198

first term, a₂ = 3 and common difference, d₂ = 5

common difference of common sequence is d₁d₂ = 3 × 5 = 15

and first common term is 8 as we can see.

common terms are ; 8, 23 , 38, 53, 68 , 83 , 98

here there are 7 common terms.
