Question

find the nth term of 1.1 2.1 3.1 4.1​

Answer 1

Step-by-step explanation:

Answer:-

Formula Used.

dn = an + 1 – an

an = a + (n–1)d

In the above sequence,

a = 1.1;

d1 = a2–a1 = 2.1–1.1 = 1

d2 = a3–a2 = 3.1–2.1 = 1

d3 = a4–a3 = 4.1–3.1 = 1

The difference in sequence is same and comes to be (1).

∴ The above sequence is A.P

The nth term of A.P is an = a + (n–1)d

an = a + (n–1)d = 1.1 + (n–1)(1)

= 1.1 + n–1

= 0.1 + n
