# Determine if the

Answer :

Formula Used.

dn = an + 1 – an

In the above sequence,

a = 5;

d1 = a2–a1 = (–5)–5 = –10

d2 = a3–a2 = 5–(–5) = 10

d3 = a4–a3 = (–5)–5 = –10

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

But the difference in sequence is not the same.

The above sequence is not A.P
