Answer 1

Given :- We have done various patterns with numbers in our previous class. Can you find a pattern for each of the following? If yes, complete them:

(a) 7,3,-1,- 5, ?

(b) -2,-4, -6, -8, ?

(c) 15, 10,5, 0, ?

(d) - 11. - 8. - 5. -2 , ?

Solution :-

(a) 7,3,-1,- 5, ?

→ 3 - 7 = (-4)

→ (-1) - 3 = (-4)

→ (-5) - (-1) = (-5) + 1 = (-4)

so, next number will be ,

→ (-5) - (4) = (-9)

(b) -2,-4, -6, -8, ?

→ (-4) - (-2) = (-4) + 2 = (-2)

→ (-6) - (-4) = (-6) + 4 = (-2)

→ (-8) - (-6) = (-8) + 6 = (-4)

so, next number will be ,

→ (-8) - (2) = (-10)

(c) 15, 10,5, 0, ?

→ 15 - 10 = 5

→ 10 - 5 = 5

→ 5 - 0 = 5

so, next number will be ,

→ 0 - 5 = (-5)

(d) - 11. - 8. - 5. -2 , ?

→ (-8) - (-11) = (-8) + 11 = 3

→ (-5) - (-8) = (-5) + 8 = 3

→ (-2) - (-5) = (-2) + 5 = 3

so, next number will be ,

→ (-2) + 3 = 1
