Noo solve the problem in English NOT KISWAHILI

Here is the solution to problem 1(a) in English: 1. (a) An arithmetic sequence is composed of numbers exactly divisible by 4, with the last number being 928. The first number is 4. Step 1: Determine the common difference. Since all numbers in the sequence are exactly divisible by 4, the common difference between consecutive numbers must be 4. d = 4 The common difference is 4. Step 2: Determine the number of terms in the series. We use the formula for the n-th term in an arithmetic sequence: L = a + (n-1)d. We have L = 928, a = 4, and d = 4. 928 &= 4 + (n-1)4 \\ 928 - 4 &= (n-1)4 \\ 924 &= 4(n-1) \\ (924)/(4) &= n-1 \\ 231 &= n-1 \\ n &= 231 + 1 \\ n &= 232 The number of terms in the series is 232. Step 3: Determine the sum of all terms. We use the formula for the sum of an arithmetic series: S_n = (n)/(2)(a + L). We have n = 232, a = 4, and L = 928. S_232 &= (232)/(2)(4 + 928) \\ S_232 &= 116(932) \\ S_232 &= 108112 The sum of all terms is 108,112. Step 4: Determine the 80th term. We use the formula for the n-th term: a_n = a + (n-1)d. We want to find the 80th term, so n = 80. We have a = 4 and d = 4. a_80 &= 4 + (80-1)4 \\ a_80 &= 4 + (79)4 \\ a_80 &= 4 + 316 \\ a_80 &= 320 The 80th term is 320.
