Yep!
Find the next term 1, 2, 4,...
Answer 8, brilliant! The interrogator is happy. But what about the simpler answer of 7?
]]>I hate such questions. It just shows the ignorance of the test writers. The sequence could have
been 1,4,16,25,1,4,16,25,1,4,16,25... or 1,4,16,25,pi,1,4,16,25,pi... or any repeating sequence
that begins with 1,4,16,25 among other possibilities like 1,4,16,25,28,30,39,... where one keeps
adding 3 then 12 then 9 repeatedly.
Also those tests that have 3 (usually) pictures and the test taker is supposed to figure out the fouth
picture (from a list of 4 or more given pictures) are faulty. Those that don't think the same way
that the test maker does have their answers counted wrong although they may have just as valid
a reason for their choice.
Some of the questions on those tests sometimes show a lack of understanding of the test taker's
creativity and intelligence.
I saw a test once that was testing quality control. Out of 100 questions 10 of them were messed
up one way or another. One of the questions was:
A stock was purchased for $100. At the end of the 1st month it had lost 50% of its value. In
the next month it gained 50% of the value it had at the end of the 1st month. How much was
the stock worth at the end of the 2nd month?
Choices
a) $100
b) $75
c) $50
d) It's hard to understand the stock market.
e) $200
Their "correct answer" was b AND d.
Go figure! How can one pass a test with such questions?
It's easy to understand the stock market: people buy and sell stocks.
PREDICTING what the stock market is another matter.
Those aptitude tests where people guess a pattern are mathematically incorrect in the sense that there are an infinite number of patterns ( equations ) from the same set of data. Each one just as valid as any other.
]]>Welcome to the fourm!
Me too. You could probably make up a rule to allow for that like:
The square numbers leaving out every third square, which seems to be your idea, but four instances are not enough to establish that rule properly.
The square numbers leaving out any square with a 9 in it would give 1,4,16,25,36,64,81, ...
I wonder if there's any clue in the source?
Where did you get it from?

]]>Welcome to the forum. I am getting that too.
]]>1,4,16,25,....,....,....any tips on the next 3 numbers.
Ive come up with 49,64,100
I could understand if there was a 9 between the 1 & 4 but it wasnt in the question.
