Answer:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.
Step-by-step explanation:
The LCM of 13 AND 17 is 221
The LCM of 40 AND 60 is 120
lcm (40; 60) = 120 = 23 × 3 × 5
An arithmetic sequence can be expressed as explicitly or recursively
The explicit formula of the sequence is
The recursive formula is given as:
Substitute 2 for n in
This gives
Calculate the common difference (d)
The explicit formula is then calculated as:
This gives
Expand
Hence, the explicit formula of the sequence is
