What is the next number of the following sequence 42, 66, 810, 1014, 1218,

Dhanraj Wanjare   9 years AGO

Ans-1422
42, 66, 810, 1014, 1218, 1422
first add 2 in first digit of first number 42's=> 4+2=6
6 is first digit of second one's first digit now same process

4+2=6
6+2=8
8+2=10
10+2=12
12+2=14
this all are the first digits of series number
next process is same as but
second time we will take second digits and add 4 in all digit like -

2 +4=6
6 +4=10
10+4=14
14+4=18
18+4=22
so
4+2=6 2 +4= 6 ==> 66;
6+2=8 6 +4= 10 ==> 810;
8+2=10 10+4=14 ==> 1014;
10+2=12 14+4=18 ==> 1418;
12+2=14 18+4=22 ==> 1422;

In the sequence the last three number differ by same number 204,so the new number will also be an increment of previous number by 204 . i.e. 1218+204=1422

Venkatesh kadali   9 years AGO

every number first digit difference is 2 thatis add 2 first number to get next first number,and every number second number difference is 4.
--->44 toadd first number by 2 and second number by 4
i.e 66.
----->66 to add first n umber by 2 and second number by 4 then we get 810
in this same way
12 18 to add first number by 2 and second number by 4 ie 14 22=1422
so answer is 1422

nidhi   9 years AGO

The first digit of all the numbers are increasing by 2 like 4,6,8,10 and 12. Therefore next digit would be 14. The last digit of the numbers are 2,6,10,14 and 18. It is clear that difference between it is 4 , means when the number is subtracted from the previous number. Here from this series next no. would be 22. So, the next number in the sequence is 1422.

neha gupta   9 years AGO

Break the terms into two parts:
like 42 as 4 and 2
66 as 6 and 6
810 as 8 and 10
1014 as 10 and 14
1218 as 12 and 18
we can easily notice the pattern as first part is incremented by 2 and second part is incremented by 4
Therefore first part of next term is 12+2=14
last part of next term is 18+4=22
thus next number is -----> 1422
