Number Series MCQs with Answers

One-liner

The next number in the sequence is $120$, as each term is obtained by multiplying the previous term by the next integer (factorial pattern).

One-liner

The next term in the series is $405$.

One-liner

The value of $x$ in the series is $3$.

One-liner

The next term in the series is $1440$, as each term is multiplied by an incrementing integer: $2 \times 2 = 4$, $4 \times 3 = 12$, $12 \times 4 = 48$, $48 \times 5 = 240$, $240 \times 6 = 1440$.

One-liner

The sum of the first $n$ even numbers is $n(n+1)$, so for $n=50$, the sum is $2550$.

One-liner

Each term is multiplied by $3$ to get the next term, so the missing term is $162$.

One-liner

The pattern multiplies each term by $2$, so the next term is $32$.

One-liner

The missing number is $125$, since the sequence consists of perfect cubes: $0^3, 1^3, 2^3, 3^3, 4^3, 5^3, 6^3$.

One-liner

The pattern follows an arithmetic progression with a common difference of $2$, so $E$ is $10$.
