What is the common ratio between successive terms in the sequence?
27, 9, 3, 1, 1927

1/3

Step-by-step explanation:

Tn = a × r^(n - 1)

T1 = a × r^(1 - 1) = a × r^0 = a = 27

T2 = a × r^(2 - 1) = a × r = 9 (equation 1)

To find the common ratio, put a as 27 in equation 1

27 × r = 9

r = 9/27 = 1/3

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
