Answer:
13
Step-by-step explanation:
where n is the number of terms, a1 is the first term and an is the last term. The sum of the first n terms of an arithmetic sequence is called an arithmetic series . Example 1: Find the sum of the first 20 terms of the arithmetic series if a1=5 and a20=62 .An arithmetic sequence is a sequence where the difference between any two consecutive terms is a constant. ... As with any recursive formula, the initial term of the sequence must be given. An explicit formula for an arithmetic sequence with common difference d is given by an=a1+d(n−1) a n = a 1 + d ( n − 1 ) .

Answer:
The entire volume would be 60m, but if it's talking only about the little rectangle on top then the answer is 6m.
Step-by-step explanation:
The length of the smaller object is 1m, the height is 2m, and the width is 3m (as seen to the right side near the bigger block).
Multiply all those numbers together (1×2=2, 2×3=6 or just simply 1×2×3=6)
