Question

1438,1429,1417,1402,? missing no. will be?

Answer 1

1438-1429= 9
1429-1417= 12
1417-1402 = 15

Therefore the difference between 1402 and the next number should be 18

Hence,

1402-18= 1384.


Hope this helps.

Answer 2

Answer:

1420

Step-by-step explanation:

Given sequence,

1438, 1429, 1417, 1402,.....

Since, the difference between the consecutive terms is small,

So, this is obvious that, there is a logic of difference,

Now,

1438 - 1429 = 9,

1429 - 1417 = 12,

1417 - 1402 = 15,

Thus, by following the pattern,

If x be the next term,

1402 - x = 18

⇒ x = 1420

Hence, missing number would be 1420.
