Which term of the progression 20 , 19 1/4 , 18 1/2 , 17 3/4 is the first negative term ?
Answered by admin @
It's a decreasing sequence. Let's find the number of term which will be zero. Then the next integer will give negative term.
answer and equating an to zero.
a = 20 , d = -3/4
an = a+(n-1)d
= 20+(n-1)(-3/4)
= 20+(-3n+3)/4
= (80-3n+3)/4
83 - 3n = 0
3n - 83 = 0
n = 83/3
n = 27.66
The next integer is 28
So 28th term will be the first -ve term....
