Answer 2

Given :- 9,19,60,305,2142,? find the next number .

Solution :-

→ 9 * 2 + 1 = 18 + 1 = 19

→ 19 * 3 + 3 = 57 + 3 = 60

→ 60 * 5 + 5 = 300 + 5 = 305

→ 305 * 7 + 7 = 2135 + 7 = 2142 .

as we can see that, we have to multiply by prime number and add odd number starting from 1 .

then, next prime number after 7 will be 11 and next odd number is 9 .

therefore,

→ 2142 * 11 + 9 = 23562 + 9 = 23571 (Ans.)

Hence, the next term will be 23571 .
