4n−10
What is the seventh term in the sequence above?
To solve for the seventh term in the sequence defined by 4n−10, we can follow these steps:
- Step 1: Identify the formula for the sequence: an=4n−10.
- Step 2: Since we need the seventh term, set n=7.
- Step 3: Substitute n=7 into the formula:
a7=4(7)−10
Step 4: Calculate 4×7=28.
Step 5: Subtract 10 from 28:
a7=28−10=18
Therefore, the seventh term in the sequence is 18.
