Answer 2

The given sequence are:

16, 30, 62, 122, 246​, ?

We have to find, the value of next number (?) is:

Solution:

The pattern follow:

(Previous number × 2) - 2, (Previous number × 2) + 2, (Previous number × 2) - 2, (Previous number × 2) + 2, .....

30 = (16 × 2) - 2

= 32 - 2 = 30

62 = (30 × 2) + 2

= 60 + 2 = 62

122 = (62 × 2) - 2

= 124 - 2 = 122

246 = (122 × 2) + 2

= 244 + 2 = 246

Similarly,

?  = (246 × 2) - 2

= 492 - 2 = 490

∴ The next number (?) = 490

Thus, the value of "next number (?) is equal to 490".
