A) determine which amounts of postage can be formed using just 3-cent and 10-cent stamps.
b) prove your answer to (a) using the principle of mathematical induction. be sure to state explicitly your inductive hypothesis in the inductive step.
c) prove your answer to (a) using strong induction. how does the inductive hypothesis in this proof differ from induction?

wait i will take screen shot please bran-list

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

3.how is solving radical equations different than solving linear equations?
