Maths and Computing:

The activity

• This activity displays a sequence of numbers
• The next value in the sequence needs to be determined
• Up to three clues can be viewed to help determine the answer

Find the next value in the sequence:

Sequence: 1 4 19 94 469

Terms are determined by multiplying the previous term by one value and subtracting another.

Sequence: 1 4 19 94 469

The difference between the terms increases by a multiple of 5

Sequence: 1 4 19 94 469

An expression for the nth term is (3 × 5^n-1 + 1)/4.

Sequence: 1 4 19 94 469

• Terms are determined by multiplying the previous term by one value and subtracting another.
• The difference between the terms increases by a multiple of 5
• An expression for the nth term is (3 × 5^n-1 + 1)/4.

The answer is 2344
