Answer 1

Answer:

649

Step-by-step explanation:

30,60,90,120,150,180 difference between them

Answer 2

Option(c) 649 is the correct answer.

Given,

Series: 19, 49, 109, 199, 319, 469, ?,859

To Find,

The missing term =?

Solution,

Firstly, we will find the difference between adjacent terms to find any pattern between them.

49 - 19 = 30 = 30 x 1

109 - 49 = 60 = 30 x 2

199 - 109 = 90 = 30 x 3

319 - 199 = 120 = 30 x 4

469 - 319 = 150 = 30 x 5

As we can see the difference between each term is increasing by multiples of 30.

The missing term will be:

Missing term - 469 = 30 x 6

Missing term = 180 + 469

Missing term = 649

For checking,

859 - 649 = 210 = 30 * 7

The 649 follows the pattern.

Hence, the missing number is 649.
