Question

what should come in the place of qus. mark......2, 31, 134, 359, ?​

Answer 1

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
