Question

Ex. 4) Find the 10th term in a geometric sequence which has a 2nd term equal to 7 and a 5th term equal to 35. [First, find the common ratio, r. Then, since the initial term, b, is not given, you must express the 10th term of the sequence in terms of one of the given terms instead. Make sure you adjust n appropriately to account for this.]

Step 1

In a geometric sequence, the \( n \)-th term can be expressed as: \[ a_n = b \cdot r^{n-1} \] where \( b \) is the first term and \( r \) is the common ratio. Show more…
