Given:
A1 = 4
Common Difference (d) = 7
Detrmine the 101st term.
n = 101
Formula for Arithmetic Sequence.
An = a1 + (n - 1) d
Solution:
Substitute the given values of a1, n and d to the formula for the arithmetic sequence.
An = a1 + (n - 1) d
A101 = 4 + (101 - 1) 7
A101 = 4 + (100)7
A101 = 4 + 700
A101 = 704
Final answer:
A101 = 704
