Ready for some mind games...
Here we go -
Bring out your
calculator and do this:
1. Take the last digit of your
phone number.
2. Multiply by 2
3. Add 5
4. Multiply by 50
5. Add 1766
6. Subtract your year of birth
7. You will get three digits
8. The first digit is the last digit
of your phone number
9. The remaining digits are your
actual age...
Any objection?
Below are some solutions to the problem I posted in a previous post.
The solutions:
The answer is 96
The first solution is
(1×4+1=5)
(2×5+2=12)
(3×6+3=21)
(8×11+8=96)
The second solution is
1st term (5=5)
2nd term (5+7=12)
3rd term (5+7+9=21)
Hence the 8th term is
(5+7+9+11+13+15+17+19=96)
The third solution is
1st term (3×3-4=5)
2nd term (4×4-4=12)
3rd term (5×5-4=21)
8th term (10×10-4=96)

With the last flight of the Anglo-French concorde more than a decade ago, civil supersonic flights have only been a dream but could that come to an end. "Yes!," I think so, and I am not the only one with such thoughts. NASA thinks it is on the right trajectory in respect of that. Maybe so but imagine flying not only under supersonic speeds (mach 2-5) but hypersonic speeds (mach 5 and above). Is it a distant reality? No, if the revolution in technological advancement catches up with the civil aviational industry, the impossible becomes possible!
