Help with GL Pack Two - Test 7
Hi
A little stuck with these two questions - any help much appreciated!
Both complete the sequence:
Q44. 12 10 9 9 10 [?]. (Ans. 12)
Q45. 10 11 11 10 8 [?]. (Ans. 5)
Thanks!

The first one is a mirror code-draw a mirror line between the two 9s and you'll see why it's 12.pixiedust101 wrote:Hi

The second one looks like +1 +0 -1-2-3 giving the answer 5.

Manana, you are perfectly correct on the second question, but I have to correct you on the first one. There are no mirror codes on these questions, and the answer to the first question works in exactly the same way as for the second one: -2, -1, -0, +1, +2, ... (and it would continue +3, +4, +5, etc).Manana wrote:The first one is a mirror code-draw a mirror line between the two 9s and you'll see why it's 12.

Pixiedust, your child needs to learn that the sequences can go "through" zero, from positive to negative and vice-versa.

Thanks for the advice Sally-Anne - I'll remind her that these are like "temperatures" and she'll know what I mean!
