Find out the next two numbers in the series.
21,24,33,60,141,_ ,_ ,..........................
Answer
Tn+1 = Tn + 3 ^ n
24 =21 + 3 ^ 1
33 =24 +(3 ^2) (3 ^2 means 3 * 3 =9)
66 =33 + (3^ 3)
141 =60 + (3^ 4)
Next two numbers 141 + (3^5) = 384
384 +(3 ^6) =1113
21,24,33,60,141, 384 , 1113 , ,..........................
