Determine whether the sequence converges or diverges. if it converges, give the limit.
108, -54, 27, negative 27 divided by 2,
can someone with this?

As you keep multiplying by -1/2, the absolute value of the next number in the sequence decreases.  As a result, the sequence converges, with limit 0 (as the lowest value in the range of absolute value is 0).

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)
