Q. State with reason, whether the sequence

12, 14, 16, 18, 22, 24, 2, 28, 32, 34, 36, 38,

Q. Assertion :Let the positive numbers

a, b, c

be in A.P., then

\frac{1}{b c}, \frac{1}{a c}, \frac{1}{a b}

are also in A.P. Reason: If each term of an A.P. is divided by

a b c

, then the resulting sequence is also in A.P.

A . P . (a, d)

denotes the set of all the terms of an infinite arithmetic progression with first term

a

and common difference

d > 0

A . P . (1, 4) \cap A . P . (1, 5) \cap A . P . (3, 3) = A . P . (a, d)
