Answer 2

Dear Student,

● Answer -

Arithmetic means = 5, 7 and 9

◆ Explaination -

# Given -

a = 3

l = 11

n = 3

# Solution -

Common difference between arithmetic means is calculated by -

d = (l-a) / (n+1)

d = (11-3) / (3+1)

d = 8 / 4

d = 2

So three arithmetic means are -

A1 = a + d

A1 = 3 + 2

A1 = 5

A1 = a + 2d

A1 = 3 + 2×2

A1 = 7

A3 = a + 3d

A3 = 3 + 2×3

A3 = 9

Therefore, three arithmetic means are 5, 7 and 9.

Thanks dear...
