According to the requirements of teenagers, the first carriage is 1 capsule. Put 2 capsules in the second compartment and 4 capsules in the third compartment. Each cell is twice as large as the previous cell, so the 2nd1cell is 2 20 =1048576.

This is a story about power, which can also be regarded as a geometric series. The first term is 1, the equation ratio is 2 and the general term formula is an = 2 (n- 1).

Properties of geometric series

1, if m, n, p, q∈N*, and m+n=p+q, then am*an=ap*aq.

2. In the geometric series, every k term is added in turn, which is still a geometric series.

3. If "G is the equal ratio mean of A and B", then "G 2 = AB (G ≠ 0)".

4. If {an} is a geometric series, the common ratio is q 1, {bn} is also a geometric series, and the common ratio is q2, then {a2n}, {A3n} ... are geometric series, and the common ratios are q12, q13 ...

5. If (an) is a geometric series and all items are positive, and the common ratio is q, then (the logarithm of an based on log) is equal, and the tolerance is the logarithm of q based on log.

6. The sum of the top n terms in geometric progression Sn = a1(1-q n)/(1-q) = a1(q n-1) =

In geometric series, the first term A 1 and the common ratio q are not zero.
