The first term of a G.P is 2 and the common ratio is 2. Find the 6th term.
a_6 = ar^5
so plug in your numbers
In GP
n- th tem is
an = a rⁿ⁻¹
a= first term
r = common ratio
a6 = a r⁶ ⁻¹
a6 = a r⁵
In this case:
a = 2
r = 2
n = 6
a6 = a r⁵
a6 = 2 • 2⁵ = 2 • 32 = 64
By the way your GP is:
2 , 4 , 8 , 16 , 32 , 64 ...
