3a^3 is the answer
Hope that helps
<span>The next letter is 'n'. The pattern misses a letter after a pair of letters, for example: 'a' and 'b' are a letter pair, then 'c' is skipped, then the letter pair 'd' and 'e' comes next. For every other letter pair, the order is reversed so they are not in alphabetical order. The next letter pair is 'm' and 'n', and because the pair 'j' and 'k' is in alphabetical order, this pair must be reversed. Therefore, the next letter is 'n'.</span>
Multiply 4 and 30. If the answer is 120, then you are correct.
Answer:
The function which represents this sequence will be:

Hence, option (A) is true.
Step-by-step explanation:
Given the sequence

An arithmetic sequence has a constant difference 'd' and is defined by

computing the differences of all the adjacent terms

As the difference is the same, so

as

Thus, substituting
,
in the nth term of an arithmetic sequence



Therefore, the function which represents this sequence will be:

Hence, option (A) is true.
