Answer 1

Answer:

answer a = b+ c and this is the answer

Answer 2

The statement $a=b+c$ is true.

Step-by-step explanation:

Decimal numeral system -

• The decimal numeral system is the accepted method for representing integer and non-integer numbers.
• It is expanding the Hindu–Arabic numeral system to non-integer values.
• Decimal notation is the term used to describe the method of representing numbers in the decimal system.

Geometric progression -

• A geometric progression sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the standard ratio.

Arithmetic progression -

• A series of numbers known as an "arithmetic progression" or "arithmetic sequence" has a constant difference between the words.

Therefore, $a=b+c$ is the true statement.
