Describe a pi bond.
a. end to end overlap of p orbitals.
b. side by side overlap of p orbitals.
c. p orbital overlapping with a d orbital.
d. overlap of two s orbitals s
e. orbital overlapping with the end of a p orbital.

a covalent bond formed between two neighboring atom's unbonded p-orbitals. double and triple bonds between atoms are usually made up of a single sigma bond and one or two pi bonds.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
