Six Nine Twenty-Seven

What is N?

6, 9, 27, 54, N, 2241

675.

The next number in the sequence is n squared minus m or f(n,m) = n2 – m
f(6,9) = 62 – 9 = 27
f(9,27) = 92 – 27 = 54
f(27,54) = 272 – 54 = 675
f(54,675) = 542 – 675 = 2241

Seconds in a Year

How many seconds are there in a year?

Hint: You don’t need a calculator

24. If you said 12 for January 2nd, February 2nd, etc that’s close, but you forgot about January 22nd, February 22nd and so on. If you are a math whiz and didn’t need a calculator to perform 60 x 60 x 24 x 365, then 31,536,000 works too. If you used 365.25 to account for leap year, then you are a human calculator, but even that’s not entirely accurate due to the leap second. And even accounting for that, it’s only an approximation that there are 365.2422 days in a year.

Hilda’s Age

When Randolph asked Hilda how old she was, Hilda replied that in two years she would be twice as old as she was five years ago. How old is Hilda?

Aside from the potential response that it’s rude to ask the age of a lady, the answer can be worked out mathematically.

x + 2 = 2(x – 5)
x + 2 = 2x – 10
x + 12 = 2x
12 = x
In two years she’ll be 14, which is twice her age 5 years ago (7).
