If the 6th term of an A. p is 11and its first term is 1 find the common diferent

Explanation:

a = 1 ... (1)

a6 = 11

Substituting the value of (1) in (2)

1 + 5d = 11

=> 5d = 10

=> d = 2

hope that helps uh..☺

Explanation:

In an AP, Tn = a + (n - 1)d

T6 = a + 5d = 11

The first term = a = 1

∴ T6 = 1 + 5d = 11

5d = 11 - 1

5d = 10

∴ d = 2

I hope this will help you :-)
