12 terms.
Sum_of_ap = n(2a + (n-1)d) ÷ 2
For 43, 39, 35, ... a = 43, d = -4
⇒ 252 = n(2 x 43 + (n - 1) x -4) ÷ 2
⇒ 252 = 45n -2n2
⇒ 2n2 - 45n + 252 = 0
⇒ (2n - 21)(n - 12) = 0
⇒ n = 101/2 or 12
101/2th terms do not make sense, so cannot be an answer. Thus 12 terms are needed.
What happens is that the sum increases whilst the terms are positive. After 10 terms, the sum is still less than 252. The 11th term is the last positive term and takes the sum over 252; the 12th term is the first negative term and takes the sum back down to 252.
To find the sum of an arithmetic progression (AP) with a common difference of -4 (since each term decreases by 4), we can use the formula for the sum of the first 'n' terms of an AP: Sn = n/2 * [2a + (n-1)d]. Here, a = 43 (the first term), d = -4 (the common difference), and Sn = 252. Substituting these values into the formula, we get 252 = n/2 * [2(43) + (n-1)(-4)]. Solving this equation will give us the number of terms 'n' that need to be taken for the sum to be 252.
The sum of the digits in 252 is 2 + 5 + 2 which equals 9.
The answer depends on how the terms and defined.

To find the sum of the first 48 terms of an arithmetic sequence, we can use the formula for the sum of an arithmetic series: Sn = n/2 * (a1 + an), where Sn is the sum of the first n terms, a1 is the first term, and an is the nth term. In this case, a1 = 2, n = 48, and an = 2 + (48-1)*2 = 96. Plugging these values into the formula, we get: S48 = 48/2 * (2 + 96) = 24 * 98 = 2352. Therefore, the sum of the first 48 terms of the given arithmetic sequence is 2352.
The sum of the digits in 252 is 2 + 5 + 2 which equals 9.
Sum of divisors of 130 = 252.

If there are three consecutive numbers which sum to 252, you can find the answer by merely dividing 252 by 3. Then take that number and the two on either side of it. So we get 84, then we take it's neighbors 83 and 85 and we're done. 252.

It means that the sum is a prime number. It says nothing about the individual terms in the sum.
The question does not make sense. The sum ad difference of two terms comprise only two terms so there are not 7 terms.
