Explanation: This is a geometric sequence, since each term after the first is obtained by multiplying a common ratio, r . The common ratio is 4 . The first term, a , is 2 . The number of terms, n is 11 . We use the formula t n = a × r n − 1 to determine the nth term in a geometric sequence. t 11 = 2 × 4 11 − 1 t 11 = 2 , 095 , 152 Hopefully this helps!
