=11+(150-1)3

=11+(149)(3)

mark as brilliant

Answer 2

Answer:

• Here, a = 11,d = 8 - 11 = - 3 Let - 150 be the nth term of the given A.P.We know that, an = a + (n - 1)d - 150 = 11 + (n - 1) × - 3 - 150 = 11 - 3n

Step-by-step explanation:

• 11, 8, 5, 2, ……….. -150 a = 11, d = 8 11 = -3. an = -150. a + (n – 1) d = an 11 + (n – 1) (-3) = -150 11 – 3n + 3 = -150 -3n + 14 = -150 ..
