The third term in an arithmetic sequence is 58 and the fifth term is 90. if the first term is a1, which is an equation for the nth term of this sequence?
1. an = 8n + 10
2. an = 8n − 14
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆3. an = 16n + 10
4. an = 16n − 38
1. an = 8n + 10
2. an = 8n − 14
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆3. an = 16n + 10
4. an = 16n − 38
Standard form is y = mx + b.
To find the slope, m, we must find the 'rise over run,' or the difference in y divided by the difference in x. We do this by:
Therefore, the slope is 8/3.
To find b, we must plug in the slope and one point:
Therefore, b is 25/9, and the total equation is
