- Divide the given numbers into 3
{49,7,98} {16, 4, 48} {9, 3, 36} {25, 5, ?}
Divide by middle term
{49, 7, 98} ----> {7, 1, 14} ---> 7*2=14
{16, 4, 48} ----> {4, 1, 12} ---> 4*3=12
{9, 3, 36} ----> {3, 1, 12} ---> 3*4=12{here middle term increasing one by one so next term similarly, just add one and multilply } then we'll get
{25, 5, ?} ----> {5, 1, x/5} ---> 5*5=25
Submit the value of x is 25 then multiply 5 --->125(ANSWER) - 10 years agoHelpfull: Yes(0) No(0)
