5 questions with worked solutions.
Q1. Complete the pattern: E2, G4, I6, K8, ?
Answer: M10
The letters follow the sequence E, G, I, K, M, which increases by 2 alphabet positions each time. The numbers follow 2, 4, 6, 8, 10, increasing by 2, so the next term is M10.
Q2. What comes next in the sequence: Z, X, V, T, ?
Answer: R
The sequence goes backward by two letters each time: Z, X, V, T. The next letter after T when moving back by two is R.
Q3. Continue the sequence: B1, E3, H5, K7, ?
Answer: N9
The letters follow the pattern B, E, H, K, which increases by 3 positions each time, so the next letter is N. The numbers go 1, 3, 5, 7, so the next number is 9.
Q4. What comes next in the sequence: Y1, V3, S5, P7, ?
Answer: M9
The letters go backward by 3 positions each time: Y, V, S, P, M. The numbers increase by 2: 1, 3, 5, 7, 9. So the next term is M9.
Q5. Continue the sequence: D1, H3, L5, P7, ?
Answer: T9
The letters progress as D, H, L, P, T, each moving forward by 4 positions in the alphabet. The numbers progress as 1, 3, 5, 7, 9, increasing by 2 each time. So the next term is T9.
