Insert Four Arithmetic Means Between 5and25 class=

Sagot :

BERCASIOBERNIE26GO

a₁ = 5

a₆ = 25

Common Difference:

d = (a₆ - a₁) / (6-1)

d = (25 - 5) / 5

d = 20 / 5

d = 4

Arithmetic Means:

a₂ = a₁ + d

a₂ = 5 + 4

a₂ = 9

a₃ = a₁ + 2d

a₃ = 5 + 2(4)

a₃ = 13

a₄ = a₁ + 3d

a₄ = 5 + 3(4)

a₄ = 17

a₅ = a₁ + 4d

a₅ = 5 + 4(4)

a₅ = 21

Thus, the 4 arithmetic means between 5 and 25 are 9, 13, 17 & 21
