Answer = 288

════════════════════

Known

U1 = 9

r = 2

════════════════════

Question

U6 = ?

════════════════════

Way to do


un = a(r {)}^(n - 1)


u6= 9(2 {)}^(6 - 1)


u6 = 9( {2}^(5) )


u6 = 9(32)


u6 = 288

════════════════════

Notes

Formula of geometric sequence


\boxed{\ un = a( {r)}^(n - 1)}

Meaning

Un = nth term

a = 1st term

r = ratio
