What should come in place of ‘?’ in the given series?

🔹 Given series:

45, 46, 50, 59, 75, ?

🔹 Find the pattern (differences):
46 - 45 = 1
50 - 46 = 4
59 - 50 = 9
75 - 59 = 16
👉 Differences are:
1, 4, 9, 16
👉 These are perfect squares:
$1^2, 2^2, 3^2, 4^2$
🔹 Next difference:
$5^2 = 25$

🔹 Next term:

75 + 25 = 100

✅ Final Answer: 100
