Some mind games...

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?

A bit of some math jokes!

Random Math Soln #1

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)
