Question

51st term of the arithmetic sequence if _1=6and d=3*

Answer 1

Let the 1st term of an arithmetic sequence is a,

& Common difference = d

Then successive terms will be a + d, a + 2d, a + 3d, …….

nth term = a + (n - 1) d

50th term of the series = 6 + (50 - 1) * 3 = 6 + 49 * 3

= 6 + 147 = 153
