Question

the next term of the sequence 1, 2, 12, 40.... is

Answer 1

(2 - (-1))* 4 = 2 + 1 = 3 * 4 = 12
(12 - 2) * 4 = 10 * 4 = 40
(40 - 12)*4 = 28 * 4 = 112.

So, the next number is 112.
The series is -1, 2, 12, 40, 112.

Answer 2

The next term of the sequence -1, 2, 12, 40,... is 112

Step-by-step explanation:

Question - Find the next term of the sequence -1, 2, 12, 40....

Given Data

-1, 2, 12, 40....

Find the next in the above mentioned series

It is clear that the given series is in the form of

[ The number - (Previous number)] × 4

The sequence starts from -1

=> [2 - (-1)] × 4 = [2 + 1] × 4 = 12

=> [12 - (2)] × 4 = [10] × 4 = 40

=> [40 - (12)] × 4 = [28] × 4 = 112

=> [112 - (40)] × 4 = [72] × 4 = 288

Therefore the next term in the given sequence, -1, 2, 12, 40...., is 112
