Indicate it as per the “Ins13, 74, 290, 650, .....​

Answer»

Answer:

1370

Step-by-step explanation:

Here we observe the first term 13 can be written as :22 +32. Similarly other NUMBERS can be written as :

74 :52 +72

290:112+132

650 : 172 +192.

Here we observe that all above term of series can be written as sum of squares of two PRIME numbers which comes next to it's previous pair.

Like : (2,3) ; (5,7) ; (11,13) ; (17,19)

So, other pair of prime number will be) 23,29. Hence next term of given series will be :

= 232+232 = 1370

So.,CORRECT answer is 1370.
