there is no unique solution.
The "92%" are obviously seeing the pattern
n + p = 2(n+p)
but with only three given elements, it's completely arbitrary to call that the "right" answer.
Here's another pattern:
Pn + 5Pn = 12n
where P1 is 1 and Pn is the nth prime number, in which case 5+25= 48, and the next element would be 7+35=60.
or
Fn + 5Fn = 12(n-2),
Where Fn is the nth element of the Fibonacci sequence (0,1,1,2,3,5,8,...) and n>2. This also would result in 5+25=48, like the prime sequence above, but the next element would be 8+40 = 60.
That psychologists routinely include these pattern-matching questions on IQ tests shows their rank incompetence and their status as failed intellectuals who couldn't pass a real math or science class. That includes the "culture-fair" picture-patterns too. They have no way of demonstrating that the "right" pattern is ever unique, even among a set of multiple choices, and can't deny that anyone who spots other patterns is probably intelligent beyond the scope of their test in the first place.
The right answer is not to answer at all. Don't give psych majors credibility by allowing them to test you. They're wrong.
There's two reasons why it would be 60.
First, as people mentioned, multiply the first equation by 5, which would result in 5(1+5)=5(12)-> 5+25=60.
The second reason would be adding the latter two equations together:
2+10=24
3+15=36
--------
5+25=60
Thus 60 is the answer.

A series is the sum of a sequence. A bunch of 1s followed by pi might be a sequence, but it's certainly not a series.

Or other variations are multiplying the third equation by 2, which is 6+30=72, and subtracting the first equation (1+5=12) which would yield 5+25=60, or add the first equation to two times the second equation (4+20=48), which would also yield 5+25=60 etc. 60 is the clear answer

Saw this online and it ticked me off that I got it wrong. The headline said 92% of us will get the answer wrong.
Here is my answer I've only read the first two responses. I'll post my answer, then I'll go ahead and read other people's responses.
Depending on the sequence/rule(s), it is either 48 or 60.
I take it back. It's 60.
I'm bored. You guys are entertaining.
All of this stuff is true modulo 6.
1+5=12=0 (mod 6)
2+10=24=0 (mod 6)
3+15=36=0 (mod 6)
5+25=30=0 (mod 6)
So CLEARLY the answer is zero. You guys all lose.
I got 60. My methodology was to subtract the first number from the second and multiply the result by 3. (5-1)(3)=12, (10-2)(3)=24, (15-3)(3)=36, therefore (25-5)(3)=60. Don't know how I came up with that solution instead of simply doubling the sum.
60
This one was not difficult
What is the 11-letter word that even the best English spellers spell incorrectly?
its 30, as other have said it doesn't change the equation just because you put a bunch of wrong equations before it. Thats not a pattern its just stupid.
Answer is 60.logic-look for a common factor that will give the initial form of 1+5=12.that will give u an insight.

incorrectly
5 + 1 actually means (5-1) x 3
10 + 2 actually means (10-2) x 3
15 + 3 actually means (15-3) x 3
20 + 4 actually means (20-4) x 3
25 + 5 actually means (25-5) x 3
...
30 + 6 = 72

Even the best English spellers have trouble with благородная.
Bad Wigins spends half the night to find ways to impress school kids on letsrun. Still he can't even figure out that 25+5=30. What a ludicrous being!

There is clearly not enough information to answer this question, though if forced to with the information given, the best answer is 60. However, your second method, which appears airtight, has the issue that you are assuming 2+3=5 and 10+15=25, though they never said these were true.

5+25 is 30. Writing a few mathematically incorrect statements before it doesn't change that fact.
There is no "if, then" statement, so 30 is correct.
