To find the common difference, we can use the formula for the n-th term of an arithmetic progression:
An = A1 + (n-1)d
Given that the 11th term (An) is 43 and the first term (A1) is 3, we can plug these values into the formula:
43 = 3 + (11-1)d
Simplifying, we have:
43 = 3 + 10d
Subtracting 3 from both sides, we have:
40 = 10d
Dividing both sides by 10, we find:
d = 4
So, the common difference of the arithmetic progression is 4.
Given that the 11th term of an arithmetic progression is 43 and the first term is 3 find;
