Question

In an Ap if T4 = 8 and a= 2 then it's common difference is .......

Answer 1

Answer:

T4

Step-by-step explanation:

T= a+(n-1)d

T4 = 2+(4-1) d

as we know that T4=8,

8= 2+3d

3d= 8-2

3d= 6

d = 6/3

d = 2

Hope u understand perfectly

Answer 2

Answer:

A4=a+(n-1)d

8=2+(4-1)d

8-2=3d

6=3d

6/3=d

2=d

d=2
