Question

4,25,144,1015,8112,?​

Answer 1

Answer:

Step-by-step explanation: 4, 25, 144, 1015, 8112, ?

Here, we see that it's an multiplication based series. ( you can find that by the rapid change in one digit to another)

now, 4,25 - here we see that 4 * 5 =20 and 20 + 5 = 25

25, 144 - here we see that 25 * 6 =150 and 150 - 6=144

144, 1015 - here we see that 144 * 7= 1008 and 1008+7 =1015

likewise for 1015,8112 - (1015 * 8) - 8=8112

so, the pattern if we see is (*5)+5, (*6)-6, (*7)+7, (*8)-8 and so on..

so answer will be (8112*9)+9 =73017
