Explanation:

The question is:

125, 129,1 20, 136, ? , 147, 98

what is in place of ?

To find, the missing number =

Th pattern follow:

$+2^{2},-3^{2}, +4^{2},-5^{2},+6^{2} ,....$

$129=125+2^{2}=125+4=129$

$120=129-3^{2}=129-9=120$

$136=120+4^{2}=120+16=136$

Similarly,

$?=136-5^{2}=136-25=111$

$147=111+6^{2}=111+36=147$

$98=147-7^{2}=147-49=98$

∴ The missing number = 111

Thus, the missing number is equal to 111.
