Question

Чому дорівнює шостий член арефметичної прогресії, перший член якої дорівнює 12, а різниця дорівнює 0,4?

Answer 1

А6=12+0.4(6-1)=12+2 = 14

Answer 2

Arithmetic Progression Calculation

The sixth term of an arithmetic progression with the first term of 12 and a common difference of 0.4 can be calculated using the formula: aₙ = a₁ + (n-1)d where: - aₙ is the nth term - a₁ is the first term - n is the term number - d is the common difference

Using the given values: - a₁ = 12 - d = 0.4

Plugging these values into the formula: a₆ = 12 + (6-1) * 0.4

This simplifies to: a₆ = 12 + 5 * 0.4 a₆ = 12 + 2 a₆ = 14

Therefore, the sixth term of the arithmetic progression is 14.
