Download Solution PDFGiven:
First term of GP = 216
Common ratio = 5/6
Find the 4th term.
Formula Used:
nth term of GP = a × rn-1
Calculation:
4th term = a × r4-1
⇒ 4th term = 216 × (5/6)3
(5/6)3 = (5 × 5 × 5) / (6 × 6 × 6)
⇒ (5/6)3 = 125 / 216
⇒ 4th term = 216 × (125 / 216)
⇒ 4th term = 125
Therefore, the 4th term of the GP is 125.
