Question

series of 8,14,42,152 ?
​

Answer 1

The answer for the missing number is 2 and for the next number is 32.

From the sequence we will find the following equation:

next number = current number + 2 * index of current number.

Hind: index is zero based

n[i + 1] = n[i] + 2 * i.

so for the new sequence 2, 4, 8, 14, 22

Ex: for number after 2 : 2 + 2 * 1 = 4

for number after 4: 4 + 2 * 2 = 8

for number after 8: 8 + 2 * 3 = 14

So on.....plz mark me as brainliest and if u like plz follow up
