Question

Write first three terms of the sequence whose nth term is defined asn^2+1


​

Answer 1

Answer:

2, 5, 10

Step-by-step explanation:

nth term = n^2+1

1 st term( n=1) gives 1+1 = 2

substitute2 and 3 for n for getting 2 nd and 3 rd term

Answer 2

Answer:

Here, cn=6n(n+1)(2n+1),∀nϵN

For n=1,c1=61(1+1)(2(1)+1)=1.

For n=2,c2=62(2+1)(4+1)=62(3)(5)=5.

Finally n=3,c3=63(3+1)(7)=6(3)(4)(7)=14.

Hence, the first three terms of the sequence are 1,5, and 14.

In the above example, we were given a formula for the general term and were able to find any particular term directly. In the following example, we shall see another way of generating a sequence
