What is a16 of the sequence 2,11,20

Mathematics
1 answer:
Rus_ich [418]4 years ago
6 0

Answer:

137

Step-by-step explanation:

This is an arithmetic sequence with first term (a₁) being 2 and common difference (d) being 11 - 2 = 9.

Explicit formula: aₙ = a₁ + (n - 1) * d so our formula is:

aₙ = 2 + (n - 1) * 9

= 2 + 9n - 9

= 9n - 7

a₁₆ = 9(16) - 7 = 137

How do I determine which is y=-1/3x+2?
Jlenok [28]

Step-by-step explanation:

This is a linear equation in slope intercept form which is

y = mx + b

where m is the slope and b is the y intercept.

The equation

y =  -  \frac{1}{3} x + 2

Has a slope of -1/3 so this means that the slope will be decreasing. A negative linear equation increases as we go left. and decreases as we go right. The y intercept is 2. So this means the graph must pass through (0,2) and when x=0, y must be 2.

In other words, look for a line that the y values increase as we go left and decrease we go right. Also look for a point (0,2) and make sure the graph pass through it.
