What is the 15th term of this Arithmetic Sequence

a₁₅ = 122

Step-by-step explanation:

Arithmetic sequence formula:

where aₙ is the nth term, a₁ is the first term, n is the index, and d is the rate of change.

For your given sequence:

a₁ is 10

n is 15 (15th term)

d is 8 (each term increases by 8 over the last)

Plug those 3 variables in, and solve for a₁₅:

you need to show the graph

step-by-step explanation:

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
