Answer 2

Answer:

Yes -25 is a term of AP

Given problem:

check whether _25 is a term of the progression 5 3 1

Step-by-step explanation:

Given data:

series AP = 5, 3, 1

here first term a = 5

common difference = T₂ - T₁ = 3-5 =-2

Here we need to check whether -25 is a term of AP

assume that -25 is nth term of AP

we know that in AP, nth term = a+(n-1)d

                                  5+(n-1)(-2) = - 25

                                      (n-1)(-2) = -25 -5

                                      (n-1)(-2) = - 30

                                           (n-1) = - 30 / -2

                                             n-1 = 15

                                                n = 16

Therefore, here we can say that -25 is 16 term of AP
