Question

check weather-150 is a term of the AP 11,8,5,2​

Answer 1

Answer:

No (-150) is not a term of the given series.

Step-by-step explanation:

First term = 11

Difference = 8 - 11 = - 3

The nth term can be determined as follows

$tn \: = a + (n - 1)d$

Assume tn = - 150

$- 150 = 11 + (n - 1) \times ( - 3)$

$- 150 - 11 = (n - 1) \times ( - 3)$

$- 161 = - 3(n - 1)$

$3(n - 1) = 161$

$(n - 1) = \frac{161}{3}$

on solving the above equation we will get the value of n in fractions therefore, - 150 is not a term of the given series.
