Question

Write common difference of ap whose nth term is 3x+5

Answer 1

here given nth term is 3x+5
an=a+(n-1)d
3x+5=a+(n-1)d
d=(3x+5-a)/(n-1)

Answer 2

Common difference of an AP is the dIifference b/w its two consecutive terms.here, first term =3+5=8. 2nd term=3×2+5=11. I.e. common difference,d=2nd term-1st term. I.e,d=11-8=3. 3 is the common difference of given AP. hope it helps....
