Answer 1

Given : a) 8,3, -2, -7,

b) 20, 12, 4,

c) -14, -10, -6,

To Find :  Complete the pattern

Solution:

a) 8,3, -2, -7,

8

8 - 5 = 3

3 - 5 = -2

-2 - 5 = -7

-7 - 5 = -12

Tₙ = Tₙ₋₁ - 5

b) 20, 12, 4,

20

20 - 8 = 12

12 - 8 = 4

4 - 8 = - 4

Tₙ = Tₙ₋₁ - 8

c) -14, -10, -6,

-14

-14 + 4 = -10

-10 + 4 = -6

-6 + 4 = - 2

Tₙ = Tₙ₋₁ +4
