For the series n3
Find the first four terms.
To solve for the first four terms of the series n3, we follow these steps:
- Step 1: Find the first term by setting n=1.
- Step 2: Use the formula n3 to calculate the cube of 1.
- Step 3: Repeat the process for the next three integers: n=2,3, and 4.
Calculations:
Step 1: For n=1
13=1
Thus, the first term is 1.
Step 2: For n=2
23=2×2×2=8
Thus, the second term is 8.
Step 3: For n=3
33=3×3×3=27
Thus, the third term is 27.
Step 4: For n=4
43=4×4×4=64
Thus, the fourth term is 64.
Therefore, the first four terms of the series n3 are: 1,8,27, and 64.
The correct multiple-choice answer is: 1,8,27,64
