Question

Is 150 a term of the A.P, 17, 12, 7, 2, …?​

Answer 1

No, 150 is not a term of the given AP

Answer 2

Answer:

d=(-5) and a=17

assume that 150 is nth term in the series then

a+(n-1)d=nth term

=>17+(n-1)(-5)=150

=>(n-1)(-5)=133

then we will get n as fraction . as n takes the value of positive integers 150 is not a term of the series.
