Question

Check whether 150is
term of AP 11852

Answer 1

Answer:

No it's not the term of given A.P

Step-by-step explanation:

Given,

a=11

d=a2-a3

=8-11

=-3

a_n=150

so,a_n=a+(n-1)d

150=11+(n-1)-3

150-11=(n-1)-3

139=-3n+3

139-3=-3n

136=-3n

n=136/-3

since,it is not divisible so it is not an term of given A.P
