1.

2,31,134,359,??What will be next no.

Answer»

Answer:

754

Step-by-step explanation:

The series is 2, 31, 134 , 359, ..

We can write this as

1+1 , 27+4 , 125+9 , 343+16 , ?

1³+1² , 3³+2² , 5³+3² , 7³ + 4² , ?

As you can SEE, the first TERM is consecutive odd numbers(cubed) ADDED to consecutive natural numbers(squared). So according to this pattern, the NEXT NUMBER should be

9³+5² = 729 + 25 = 754
