Answer :

Formula Used.

d_{n} = a_{n + 1} – a_{n}

a_{n} = a + (n–1)d

The sequence of natural numbers which are multiple of 3 or 5

in increasing order

Is 3, 5, 6, 9, 10 ……

In the above sequence,

a = 3;

d_{1} = a_{2}–a_{1} = 5–3 = 2

d_{2} = a_{3}–a_{2} = 6–5 = 1

d_{3} = a_{4}–a_{3} = 9–6 = 3

⇒ As in A.P the difference between the 2 terms is always constant

The difference in sequence is not same .

∴ The above sequence is not A.P
