Explanation:

Let’s break it down:

- The sequence you have is: 8  5  47  6  812  20  1244  10  ?

- At first glance, the numbers look random, but look at how some might be paired: (8, 5), (47, 6), (812, 20), (1244, 10)

- Now, look closer: 8 × 5 + 7 = 47

Next: 8 + 12 = 20 

- So, for the pair (812, 20), looks like: (8 + 12 = 20)

- For (1244, 10), 12 + 44 = 56 (doesn’t match 10)

- Let's consider another angle:

- If you split 812 as 8 and 12, then add: 8 + 12 = 20 (matches)

- 1244 as 12 and 44, add: 12 + 44 = 56 (still doesn’t match 10)

- But maybe the rule is, split the big number: sum the parts (for 812: 8+12=20, for 1244: 12+44=56)

- Next number should then be 56.

So your answer was option 3 (20), but the pattern says the answer should be the sum of the split parts of 1244— so 12+44=56.

But there’s no 56 in the options.

Let’s check the options:

- Option 1: 30

- Option 2: 40

- Option 3: 20

- Option 4: 35

There’s a mismatch in the sequence or options. If we check the first pairing: (8, 5) is not 8+5, could it be 8*5=40? No. Is it 8*5+7=47? That adds randomly.

But for (812, 20), it’s clearly adding the two numbers formed by breaking apart the digits: 8+12=20.

So, logically, the answer following 1244 would be 12+44=56 (if we stick to this pattern), but since none of the options match, the closest logic is matching the sum parts (and there’s no 56). If we must pick from the list, none really fits.

- Here’s the thing: The main pattern is adding split numbers, but the available options don’t have the correct answer.

- If required to choose, none aligns perfectly, so this question seems flawed from a logical patterning standpoint.

So, to recap:

- Split 812 = 8 and 12 ? 20 (matches)

- Split 1244 = 12 and 44 ? 56 (no match in options)

If you picked option 3 (20), that fits for 812, but not after 1244.

So:
