write c++ code using only if else statement

Problem 3 [10 pts] Write a pseudo-code that prints the first n terms of the Tick-Tock series. The value of nis taken as input. The first 8 terms of the Tick-Tock series, i.e., for n=8 are as follows: 2-5 +4 -10 + 6 - 15 + 8 - 20 Can you guess the pattern? The odd terms are multiples of 2 and in increasing order (2, 4, 6, 8 etc.). The even terms are increasing multiples of 5 and in negative form. The terms are alternatively positive and negative. Nothing should be printed if the value of n is below 1. For Example: if the input is ne5, the pseudo-code prints: 2-5-4-10 + 6 if input is n=10, the pseudo-code prints: 2-5+4 -10 + 6-15 +8-20 + 10 - 25 Problem 2 [5 pts] Give the output of the following code extra extra = 0 READ extra; if (extra
