the record holder is 5.58 m.
3rd box is the answer
the given series converges and
given is 108, -18,
it is an alternate series. an alternate series is convergent if:
1. the series is decreasing.
2. if the last term (n-th term) of series converges to 0.
since each next term is less than its preceding term, so it is decreasing.
first term, a = 108
second term = -18
common ratio, r = -18/108 = -1/6
general term, aₙ = a*rⁿ = 108*(-1/6)ⁿ
when n increases to infinity, the exponent term will decreases to zero, and last term (n-th term) will converge to 0 as well.
hence, the given series converges.
now limit will be:
