(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

t1, t2, t3, t4 , ...... , tn is a sequence

t2 - t1 = t3 - t2 = t4 - t3 .............. = t(n-1) - tn

show that:

1/t_{1}t_{2}+ 1/t_{2}t_{3}+ 1/t_{3}t_{4}............... + 1/t_{n-1}t_{n}= n-1/t1tn

2. Relevant equations

3. The attempt at a solution

I tried to use sigma but I couldn't solve it ..

Please give me the beginning of the solution
