To find the sum of 25 terms of these arithmetic sequence you can use the formula:Sn = (n/2)(a1 + an), where n is the number of terms in the sequence, a1 is the first term, and an is the last term of the sequence. In our case n = 25, so we need to compute a1 and a25.Since an = 5t - 3, thena1 = 5(1) - 3 = 5 - 3 = 2a25 = 5(25) - 3 = 125 - 3 = 122By substituting the values we know into the formula we have:S25 = (25/2)(2 + 122) = (25/2)(124) = 25 x 62 = 1,550Or you can use the formula:Sn = (n/2)[2a1 + (n - 1)d] where d is the common difference.In order to find d, we need to find at least the value of 2 terms and subtract them.a1 = 2a2 = 5(2) - 3 = 10 - 3 = 7So d = 7 - 2 = 5By substituting the values we know into the formula we have:S25 = (25/2)[2(2) + (25 - 1)5]S25 = (25/2)(4+ 120) = (25/2)(124 = 25 x 62 = 1,550Thus, the sum of 25 terms of the given arithmetic sequence is 1,550.

124 inches = 10.333 feet = 3.444 yd 4 yd is bigger
2x2x2x2x2x2x2x2 = 256
The answer is half the measure, 62°. Have a nice day!

The term common factors specifically refers to the factors shared by two or more numbers. Since 124 is a single number, you could say that it shares all of its factors with itself.The factors of 124 are: 1, 2, 4, 31, 62, and 124.

Imagine instead that your equation is (124/10) * (31/10), or, all things being commutative in multiplication, (124 * 31) * (1/10 * 1/10) = (124 * 31) * (1/100) = (124 * 31) / 100. Multiply the first term, and you get 3844. Once you divide from there, you get 38.44.
124/124 = 1 124/62 = 2 124/31 = 4 124/4 = 31 124/2 = 62 124/1 = 124
The multiples of 124 between 1 and 10 are:1 x 124 = 1242 x 124 = 2483 x 124 = 3724 x 124 = 4965 x 124 = 6206 x 124 = 7447 x 124 = 8688 x 124 = 9929 x 124 = 111610 x 124 = 1240
