Question
A series is given with one term missing. Choose the
correct alternatives from the given ones that will complete the series. 21, 46, 82, 131, 195, ____Solution
The logic followed here is: 21 + 5² = 21 + 25 = 46 46 + 6² = 46 + 36 = 82 82 + 7² = 82 + 49 = 131 131 + 8² = 131 + 64 = 195 195 + 9² = 195 + 81 = 276
If x − 1/x = 4, find x² + 1/x²
Solve for x:
2(x + 1) × 4(x − 2) = 32
Simplify:
(√5 + √2)/(√5 − √2) + (√5 − √2)/(√5 + √2)
If 100.9 = 12 and ( 0.1)x = 120, then what is the value of x.

If (9000) 5 = 59.049
Evaluate:
[1 / (3 + √5)] + [1 / (3 − √5)]
If 100.13 = 14 and ( 0.1)x = 140, then what is the value of x.
