1. Add: \( 39+402 \) 2. Solve: \( 3 x+4=13 \) 3. Express 5024 in words. Find the next number in the sequence: \( 1,4,2,5,3 \). 4.

The sum of \( 39 + 402 \) is \( 441 \). Simple addition can be a breeze if you line up the numbers properly, starting from the rightmost digits. To solve the equation \( 3x + 4 = 13 \), subtract \( 4 \) from both sides to obtain \( 3x = 9 \), and then divide by \( 3 \) to find \( x = 3 \). Remember to always isolate the variable by performing the same operation on both sides! The number 5024 in words is "five thousand twenty-four." Writing numbers in words can be quite fun, as it brings a bit of a story to the figures! In the provided sequence \( 1, 4, 2, 5, 3 \), the next number is \( 6 \). The pattern alternates between increasing and decreasing by one—first we go up by 3, drop by 2, then rise by 3, and drop again by 2, leading us to 6 next!
