Question

Find the indicated term of the given geometric sequence. a = 14, r = –2, n = 11

Answer 1

Answer:

-14336

Step-by-step explanation:

We are given the first term (a) = 14, the common ratio (r) = -2 and the number of term (n) = 11 that we are to find for a geometric sequence.

We know that the formula of nth term for a geometric sequence is given by:

$n^{th}term = ar^{n-1}$

Substituting the given values in the above formula to find the 11th term:

11th term = $14 \times 2^{11-1}$ = -14336
