The first four terms of a sequence are shown below:
8,5, 2, -1
which of the following functions best defines this sequence?
of(1) = 8, f(n + 1) = f(n) + 3; for n 2 1
of(1) = 8, f(n + 1) = f(n) - 5; for n > 1
of(1) = 8. f(n + 1) = f(n) + 5; for n 2 1
f(1) = 8. f(n + 1) = f(n) - 3. for n 2 1

How many people are we starting with? i will answer it's just i need to divide 8 by the total amount of people to get how many tables

Idon't know the answer

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
