Zero-Exponent Rule: a0 = 1, this says that anything raised to the zero power is 1. ... Negative Exponent Rule: , this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents.
Let's represent the numbers by : x, x+1, x+2, x+3 x+x+1+x+2+x+3=40 The third number in the sequence is x+2 4x+6=40 8.5+2=10.5 4x+6-6=40-6 Therefore the third number in the sequence is 4x=34 10.5 4x/4=34/4 x=8.5
