Here,first value (a)=-4

Second value(A2)=-1

Common difference (D)=A2-a1

=-1-(-4)=-1+4=3

Hence,Our common difference is 3 ;a=-4

We have to find the 27th term

$\bold{\blue{= > 27th \: term = a + 26d}}$

=>-4+26×3

=>-4+78=$\bold{\red{74}}$

Therefore,The 27th term of the arithmetic sequence -4,-1,2,5,8 is 74
