One-third of 2c subtracted from five times nine

1 answer:

4 0

One-third of 2c subtracted from five times nine
1/3 of 2c subtracted 5 x nine
1/3 x 2c - 5(9)
=1/3 x 2c - 45
=2c/3 - 45
if we solve for c,
2c/3 = 45
2c = 45 x 3
2c = 135
c = 135/2
c = 67.5

A)clara believes the sequence 3,9,27,81,243 is arithmetic. Do you agree with clara?Explain your reasoning.

allsm [11]

This is NOT an arithmetic sequence because there is no common difference. It is a geometric sequence because there is a common ratio. Meaning that each term is a constant ratio or multiple of the previous term. The recursive rule for this geometric sequence is:

a(n)=3*a(n-1), a(1)=3
