Question

(x+5) is an even number . Which will be the 12th preceding odd number?​

Answer 1

Answer:

If (x+5) is even Then (x+4) is odd , Similarly (x+2) is also odd..

This makes an AP: (x+4), (x+2)......

Its 12th term will be:

a12 = a + (12-1)d

      = x+4 + 11*(-2)

      = x+4 - 22

      = x-18

So, Your Answer Is (x-18)
