The first term of the arithmetic progression is – 7.4, and the difference is 1.8. Find the first five members of the progression.

Let us find out what value the second term of the indicated progression will take when we know from the condition of the task that its difference is equal to 1.8:

-7.4 + 1.8 = -5.6.

Let’s find out what value the third term of the indicated progression will take:

-5.6 + 1.8 = -3.8.

Let’s find out what value the fourth term of the indicated progression will take:

-3.8 + 1.8 = -2.

Let’s find out what value the fifth term of the indicated progression will take:

-2 + 1.8 = -0.2.

Answer: First term = -7.4; second = -5.6; third = -3.8; fourth = -2; fifth = -0.2.
