WebOn a higher level, if we assess a succession of numbers, x 1, x 2, x 3, . . . , x k, we can record the sum of these numbers in the following way: x 1 + x 2 + x 3 + . . . + x k . A simpler method of representing this is to use the term x n to denote the general term of the sequence , as follows: WebThe recursive case implies that the total sum is the first value, numbers[0], plus the sum of the rest of the values, numbers[1:]. ... 1 × 4 + 2 × 5 + 3 × 6 = 32. To extract successive pairs of values from the input sequences, you can use zip(). Then you can use a generator expression to multiply each pair of values.
