Question

Find the missing term in the series given below 3,12,25,42?88

Answer 1

63

Explanation:

the value of the difference between the terms increases by 4 as the series continues.

basically, this shows that the difference between 3 and 12 is 9, the difference between 12 and 25 is 13 (which is 4 more than 9), the difference between 25 and 42 is 17 (which is 4 more than 12), and so on.

using this pattern, all we have to do is find the next difference- the one between 42 and the missing term.

to do this, we take the previous difference, 17, and add 4. this gives us 21.

we then add 21 to 42 to get the next term: 63.

hope this helped, good luck!
