38 × 7 = 266
The 50th term in the sequence is 199
Arithmetic sequence
The nth term of an arithmetic sequence is expressed as:
Tn = a+ (n - 1)d
where:
- a is the first term
- n is the number of terms
- d is the common difference
The sequence formed by the amount of Whatchamacallits produced as;
3, 7, 11, 15...
a = 3
d = 11-7 = 7-3 = 4
Substitute
Tn = 3 + (n-1) * 4
Tn = 3 + 4n -4
Tn = 4n - 1
Hence the explicit formula that models the production for the nth term of the sequence is Tn = 4n - 1
If n = 50
T50 = 4(50) - 1
T50 = 199
Hence the 50th term in the sequence is 199

The radius of the circle is 1km
3 water bottles.
1 liter is the same as 1,000 milliliters. So, the water jug can hold 6,000 milliliters of liquid.
Simple divide 6,000/2,000, which is the same as 6/2, to get 3. So, the water jug needs 3 water bottles of liquid to fill it.
