Seventh grade math problem: according to the requirements of teenagers, put 1 ten thousand grains of wheat in the second1square of the chessboard. Is it too much or too little? Why?
Less. The 2nd1box needs to hold 1048576 grains of wheat, and the 2nd1box can't hold1million grains of wheat.

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.
