Question

if an=2n-3/6 then find 10th term

Answer 1

an= 2n-3 ,for 10th tem n=10

a10= 2*10-3/6=17/6

Answer 2

Answer:

Step-by-step explanation:

an=(2n-3)/6

Putting n=1,2,3,4,......

a1=(2×1-3)/6=-1/6

a2=(2×2-3)/6

=1/6

............................

a=-1/6

d=1/6-(-1/6)

=1/6+1/6

=2/6

=1/3

a10=-1/6+(10-1)×1/3

=-1/6+9×1/3

=-1/6+3

=-1+18)/6

=17/6
