Question

Find the first positive term of the A.P: -11, -8, -5,.......

Answer 1

Given -
The terms ( -11, -8, -5,....) are in A.P

here common difference (d) = 2nd term - 1st term
                                                 =  -8 - (-11)   =  -8+11  = 3

So, The 4th term is =last term + common difference = -5 +3 = -2

now next term (5th term ) = -2 + 3 =1

Hence the first positive term of this A.P is 1.

Answer 2

Answer: 1

Step-by-step explanation:

• Given first term (a)=(-11) and common difference(d)=(-8)-(-11)

                                                                                                 =3

• 4th term= a+3d

                       = -11+9

                       = -2

• 5th term= a+4d

                       = -11+12

                       = 1

• Hence,the first positive term of the given A.P. is 1.
