Question

2. Show that the sequence, defined by its n'h term
[a+a,] , forms an AP. Also, find the common difference
of it.​

Answer 1

Answer:

To find that

sequence defined by n'h term and difference and to form an a.p.

we have -

an=a+(n-1)d

suppose if we hiding the an (n'h)then

a+(n-1)d =this is show only one term and a.p. not contain only one term that's why n'h(an) is needed to show an a.p.

difference is ak+1 ak

A.P.= take a=1,d=1andn=11 therefore

an=1+(11-1)1=

1+(10)1=

1+10

so,11 is answer
