Answer:
9√2 or √162
Step-by-step explanation:
Given series
√18, √50, √98,.....
√9×2,√25×2,√49×2,....
3√2, 5√2, 7√2, ..
a=3√2
d=5√2 - 3√2
d=2√2
hence next term is 7√2+d=7√2+2√2=9√2
9✓2 or √81×2=√162

√18 can be written as 3√2
√50 can be written as 5√2
√98 can be written as 7√2
hence, the AP becomes, 3√2, 5√2, 7√2......
now the common difference 5√2-3√2 = 2√2
hence, the next term is 7√2+2√2 = 9√2 or √162
