DS1 Mathematical Induction No. 3-5 3.Induction is a variant of induction, in which we assume that the statement holds for allthe values preceding k.4. Prove that given any integer for n, n3 + 2n will be divisible by 3.5. Write the formal proof that 2"+2 + 32n+1 is divisible by 7 for all positive integers.

How many different arrangements of the beads can you make?" Elizabeth solves the problem by finding the number of distinguishable permutations of 30 objects, 18 alike of one kind and 12 alike of another kind. That is, she uses the result of the previous problem. Natalie solves the problem by finding the number of combinations of 30 different objects taken 18 at a time. Who is correct?
