Answer 2

Answer:

55th term

Step-by-step explanation:

First term, a = 11,

Common difference = 8 - 11 = - 3,

Let -151 is the nth term of the AP,

then,

$nth \: term \: = a + (n - 1) \times d$

$- 151 = 11 + (n - 1) \times ( - 3)$

$- 151 - 11 = ( - 3)(n - 1)$

$\frac{ - 162}{ - 3} = (n - 1)$

$n - 1 = 54$

$n = 55$
