Question
In the following question, select the missing number
from the given series. 48, 54, ?, 75, 90, 108Solution
The difference between the numbers in the given series is consecutive multiple of '3' starting from '6'. 48 + 6 = 54 54 + 9 = 63 63 + 12 = 75 75 + 15 = 90 90 + 18 = 108
Given that x8-34x4+1=0, x>0. What is the value of (x3+ x-3)?
Simplify the expression:
3x + 5y - [(7x + 3y) - (2x + y) + 4y] - x(288 ÷ 8)² × (144 ÷ 24)³ = 24 × ? × (51840 ÷ 20)
