Find the missing term: 7, 26, 63, 124, 215, ?

  1. 342
  2. 350
  3. 300
  4. 330
Show answer and solution

Correct answer: A. 342

1. Observe pattern: 7 = 2^3 - 1, 26 = 3^3 - 1, 63 = 4^3 - 1. 2. Continue: 124 = 5^3 - 1, 215 = 6^3 - 1. 3. Next term: 7^3 - 1 = 343 - 1 = 342. 4. So the missing term is 342. _Source: ICAI BoS Foundation Paper 3, Ch 9, p.3 worked examples_

Find the next term: 2, 4, 8, 16, 32, ?

  1. 62
  2. 64
  3. 40
  4. 48
Show answer and solution

Correct answer: B. 64

1. Each term doubles the previous: 4 = 2*2, 8 = 4*2, 16 = 8*2. 2. Geometric series with common ratio 2. 3. Next term = 32 * 2 = 64. 4. So the missing term is 64. _Source: ICAI BoS Foundation Paper 3, Ch 9, p.3_

In a code FRIEND = HUMJTK, the code for CANDLE is

  1. DBOEMF
  2. EBQFNK
  3. EDRIRL
  4. FDQHRI
Show answer and solution

Correct answer: C. EDRIRL

1. Map letters: F(+2)=H, R(+3)=U, I(+4)=M, E(+5)=J, N(+6)=T, D(+7)=K. 2. So shifts are +2, +3, +4, +5, +6, +7. 3. Apply to CANDLE: C+2=E, A+3=D, N+4=R, D+5=I, L+6=R, E+7=L. 4. Result: EDRIRL. _Source: ICAI BoS Foundation Paper 3, Ch 9 'Coding', p.6_
