The formula for the triangular sequence is Xn=n(n+1)/2
So X25=25(25+1)/2=325

I believe the answer is 34. I plugged the values into the STAT button on my graphing calculator and went into 1-Var Stats.
40 percent is your answer. The fraction form would be 2/5 or 4/10. 4/10= to 40%
The answer is 12! It is basically the same as asking (-1)(-12) which is 12 because when multiplying two negatives you get a positive!
3/4 - 2*(1/8) = 6/8 -2/8 = 4/8 = 1/2
