• M Rajagopala Rao

8 = 7×8 = 56
7 = 6×7 = 42
6 = 5×6 = 30
5 = 4×5 = 20
4 = 3×4 = 12
3 = 2×3 = 6

• Roger

The answer to 3=? is 6, I believe.

• martin

3=6

(x + 1) * ( x + 2)

• Caiman Cotton

The next number is six, as it goes down in order of multiplication, so 4 would be multiplied by 3, and 3 by 2.

Viewed another way, each number is multiplied by the whole number directly below it.

• Munish Kishore

The answer seems to be 6
3×2 =6
4×3 = 12
5×4 = 20
6×5 = 30
7×6 = 42
8×7 = 56

3*3=9 is it wright? Am I right?

• Karen

The answer to the Math logic question is 3=9

• Karen

opps correction 3=6

• J

How about 9? Unless there is another pattern I’m not seeing….

• Jane

8*7
7*6
6*5
5*4
4*3

3*2=6

• SOLOMON

IF
8=56
7=42
6=30
5=20
THEN
3=6

3 is equak to 9

• takisha

8=56
7=42
6=30
5=20
3=9

• Nelson D'Souza

8=56 (8×7)
7=42 (7×6)

3=6 (3×2)

• Robert

6.

8×7=56
7×6=42
6×5=30

Therefore, 3x(3-1) = 3×2= 6

• mitko

8 x 7 = 56
7 x 6 = 42
6 x 5 = 30
5 x 4 = 20
3 x 2 = 6
Hence, 3 = 6

• Eamon

My IQ is not terribly but the next number in the sequence is 4 as in 4=12. The missing number however is 6 as in 3=6

• Ray

6

and now I need to put some extra words in because a single letter comment isn’t accepted by this web engine.

When I’m not checking out blogs like this I run a product development company that designs other people’s products for them. We focus on electronics based products for manufacturers in developed nations that want to continue making their products where they are but need to compete internationally. Some examples of our current projects are:
- Pet training product for dogs left indoors, alone, during the day
- remote water metering (uses 2G/3G/4G/GSM for communications)
- battery operated metering
- several IoT (Internet of Things) appliances
- 2.5KW 40VDC BLDC motor controller
- pneumatic controller for a hydraulic winch
- industrial pump controller

there, that should be enough text. Just to make sure, I’ll add a nice big signature. That should do it.

Following the sequence given, I think the answer is 6…if it’s not a trick question.
