Question

ls -150 a term of the AP 17, 12, 7, 2...?​

Answer 1

Step-by-step explanation:

a = 17

d = -5

n = 150

150th term = a + (n - 1 )d

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

= 17 + 149× (-5)

= 17 + ( - 745 )

= -728 Ans...

Answer 2

Answer:

a=17 , d=12-17=-5

by an = a+(n-1)d

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

-150= 17 -5n +5

-150= 22-5n

-150-22=-5n

-172= -5n

n=172/5

n=34.4

so, -150 is not a part of given ap
