Question

If a = 8, an = 206, n= 23, then value of 'd' should be

Answer 1

Answer:

d = 9

Step-by-step explanation:

An = a + (n - 1) d

Given,

a = 8

An = 206

n = 23

Therefore,

206 = 8 + (23 - 1)d

206 - 8 = 22 d

198/22 = 9

Answer 2

Answer:

9

Step-by-step explanation:

an= a+(n-1)d

206=8+(23-1)d

206-8=22d

198/22=d

d=9
