Indicate a general rule for the nth term of this sequence. -6b, -3b, 0b, 3b, 6b. . .

The general rule for the nth term of the sequence is

Explanation:

The sequence is -6b, -3b, 0b, 3b, 6b, .....

To find the nth term of the sequence, we need to find the common difference and the first term of the sequence.

First term of the sequence = -6b

Common difference =

Using this the nth term of the sequence can be determined.

Since, this is an arithmetic sequence, the general form of AP is given by the formula,

where a denotes the first term of the sequence and d denotes the common difference. Thus, and

Substituting the values in the general formula, we get,

Thus, the general rule for the nth term of the sequence is

its 4 because 2 times 2 is 4, if you double the number two you get four

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
