Find the number of terms and the sum of the terms of the arithmetic progressions 32,28,….4a.14 : 252b.8 : 144c.15 : 270d.7 : 126
Question
Solution 1
Sure, let's solve this step by step:
a. 32, 28, …, 4
The common difference (d) here is 28 - 32 = -4. The first term (a) is 32 and the last term (l) is 4.
The number of terms (n) in an arithmetic progression can be found using the formula: n = [(l - a) / d] + 1
So, n = [(4 - 32) / -4] + 1 = 8
